forward-port from rel-2-2-dev: (update copyright date range -- 2000-2006.
this is probably overkill, since there are some files that were created
after 2000 and some files that were last modified before 2006.)

Preliminary commit of changes to add Gateway module.
This adds to WeBWorK
- the ability to create versioned, timed problem sets ("gateway tests")
for which all problems are displayed on a single page ("versioned"
means that students can get multiple versions of the problem set),
- the ability to create sets that draw problems from groups of
problems, and
- the ability to create sets that require a proctor login to start
and grade.
Sets can be defined as gateway tests or proctored gateway tests from
the ProblemSetDetail page.
Not quite bug-free yet. Known bugs include handling of problem values
on the Student Progress page (I think this may be a problem with
changing from sql database format where all entries were 'text' to
sql_single in ver 2.1, where they are integer), and a division by zero
error on the grades page (which may be the same problem).
Tests with a number of attempts per version greater than one haven't
been carefully tested, nor has scoring of gateway tests.

Changes needed to make loadMacros() look through a path of directories
rather than just course/templates/macros and pg/macros. You can
specify the path in the global.conf file.
You also need to make the update to pg/macros/dangerousMacros.pl

Added ability to control the "Missing TeX Fonts" message generated by
jsMath. There are now two parameters in global.conf that control the
message. You can set
$pg{displayModeOptions}{jsMath}{reportMissingFonts}
to 0 if you want no font messages, and you can set
$pg{displayModeOptions}{jsMath}{missingFontMessage}
to a string that should be issued when the fonts are missing. This
can be an HTML string, so you can include a link to the jsMath font
page, as the current message does. The message will be set in a <DIV>
of class NoFontMessage, so the style attributes can be controled in
the content-generators template file.

Improved error message reporting in PG and in the main WeBWorK
dispatcher. If an error is trapped by the main dispatcher, it now
prints a complete stack trace for the error.
Note that the PG error reporting also requires an update to the pg
tree as well, so be sure you update both trees.

removed lingering references to "webwork-modperl", since we're calling
this product "webwork2" now. soon we should change the name of the CVS
module to "webwork2" as well.

Normalized headers. All files now contain the text below as a header.
This is important since all files now (a) use the full name of the
package, (b) assign copyright to "The WeBWorK Project", (c) give the
full path of the file (relative to CVSROOT) instead of simply the file
name, and (d) include license and warranty information.
Here is the new header:

Rewrote ImageGenerator to work with WeBWorK2. Its arguments are now
passed in via an options hash instead of getting a whole %envir. Also,
the options are passed to the constructor and there is no initialize()
method. add() has the same interface, and render() has been changed
slightly. (This closes Bug #80!)
To make this work with 1.8, take a look at how I'm creating
ImageGenerator in &WeBWorK::PG::defineProblemEnvironment and make the
necessary modifications to processProblem8.pl.
I made changes to WeBWorK::PG to have "images" mode trigger HTML_dpng
rather than HTML_img, and also to create an ImageGenerator before
initializing and call render() after translation.
Also in PG, I shortened the names of the equation image files. They're
now "equation-$PSVN-$probnum-$seed.png". This has the added benefit of
forcing image regeneration if the problem seed changes, closing Bug
#70.
Equation files are now dumped directly into the $courseDirs{HTML_temp}
directory. This means that no one has to worry about whether "m2i"
exists any more.
global.conf.dist was changed to not include the switches to dvipng on
the command line (they're currently hardcoded into ImageGenerator).
I still have to get this to work with dvipng 0.3. I should also take
advantages of 0.3's new features, like pipelining (using the -follow
switch) and specifying the output file name (to avoid the "move" of
resulting images).
This is MUCH FASTER than the way I was calling dvipng, and I think it's
safe to say that it's a better method. Thanks JJ!

Problem Editor now creates a temporary file to edit (
adding .tmp to the file name)
Refresh causes a redirect to the Problem.pm with a GET command.
Some of the arguments are unnecessary and need to be cleaned up.
The seed and display mode in the problem editor are not properly
initialized from the problem set.
Problem.pm has been modified to check for these arguments and to read
the temporary source file, seed and displayMode. These are passed
through to a PG.pm object.
PG also needed to be modified so that the source_file and seed values
are overridden

DONE effectiveUser for at least Problem.pm
DONE write a template escape for printing $user, $effectiveUser, &c. nicely
also added additional timing log points: timing is now logged:
1. when WeBWorK::PG::new starts
2. after all the initialization-type stuff happens
3. when WeBWorK::PG::new ends
Getting it to log the entire request time might be a little harder.

- created macros/IO.pl, which is loaded with no opmask by PG.pm. It is a copy
of WeBWorK::PG::IO.pm, with some changes to make it work as a macro package.
The translator no longer shares IO.pm's functions with the safe compartment.
This is a BAD THING, and should be reconsidered when the Translator is
revised.
- Changed many (but not all) checks for HTML or HTML_tth modes to match /^HTML/
in the macros.
- changed &header to &head in Problem.pm
- Added problem environment variables for gif2eps and png2eps and modified
&dangerousMacros::alias to use them
- fixed MOST of the harmless warnings in the system. there's still the "Use
of uninitialized value in null operation" warning in template(), tho.
Still to come:
- make images in PDFs work
- fix TTH mode character encodings on mac (maybe)
- have logout button invalidate key
- Pretty die messages (from outside of the translator)
- Feedback - need nice modular way of sending email
- Options - email address and password

"normalized" files:
- (c) header on all files
- standard order of preamble lines:
1. (c) header
2. package PACKAGENAME;
3. short summary of the package (pod's NAME section)
4. use - pragmatic modules
5. use - standard perl modules
6. use - CPAN modules
7. use - webwork modules
- ALWAYS use strict and use warnings
- use "use base" rather than "our @ISA"
so now we can be happy.

added refreshMath2img to the problem environment (PG.pm) and modified
Problem.pm to set it when showHints or showSolutions is on. THIS IS NOT
THE BEST THING TO DO -- we only need to refresh when the value of
showHints or showSolutions CHANGES. Also, we should be refreshing if the
problem seed changes. So, we need somewhere to store those three values
between invocations of the script. HHHHHMMMMMMMM......... &math2img in
dangerousMacros.pl has been modified to respect refreshMath2img and also
refresh if the image file is older than the PG source file.
