Resolve bug #994 ("Try it" yields: sourceFilePath is unsafe!)
SetMaker uses a relative path for sourceFilePath, which is nice, but
which path_is_subdir didn't account for. Added thrid argument,
$allow_relative, to that utility which causes $dir to be prepended to
$path. Modified Problem.pm to trigger this behavior.

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.

Fixed a bug in which the constant 'function' BASE64_ENCODED was not being
evaluated inside the matching and substitution statements. Replaced
the constant by using the construction
our $BASE64_ENCODED = 'base64_encoded:';
instead. The variable is properly interpolated inside the matching
and substitution statements.

complete rewrite of parseDateTime to close bug #693.
- using modified version of WW1's unformatDateAndTime() function for
actual parsing.
- intelligent treatment of two, three, and four digit years consistent
with Time::Local.
- attempt to interpret time zone specification using DateTime::TimeZone
and then Time::Zone. if neither succeeds, an expection is thrown.
- if timezone is not specified, $display_tz is actually used.
It never ceases to amaze me how tricky time zone handling is. It appears
that I have it right now, but please test.

PRELIMINARY SUPPORT FOR TIME ZONES (towards closing bug #532).
(1) new configuration variable $siteDefaults{timezone}
Set the default timezone of courses on this server. This must be a value
valid for the TZ environment variable. See also tzset(3).
If left blank, the system timezone will be used. This is usually what
you want. You might want to set this if your server is NOT in the same
timezone as your school. If just a few courses are in a different
timezone, set this in course.conf for the affected courses instead.
(2) support for second optional $display_tz argument to formatDateTime()
and parseDateTime().
If specified, formatted string datetimes will be considered to be in
that timezone instead of the server's local timezone.
Remaining work:
find all calls to *DateTime() and add the $client_tz argument.
$client_tz is is really something that *DateTime() should be able to
grab out of $ce, but they're not a method on ContentGenerator, so we
have to pass it in. It might be worth moving them to ContentGenerator.
(Or some new subclass of ContentGenerator or something?)

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:

Modified parseDateTime so that it handles time strings of the form
01/03/03 at 06:00am. The " at " retains compatibility with webwork 1.9
which is important for import and export. This fixes a bug introduced
when changing formatDateTime. #204 and #203 should be fixed by this.

Added " at " in formatDateTime function. This makes it compatible with webwork1.9
which is important when we export set definition files. this may ruin
some earlier aesthetic considerations (Dennis?) but the compatibility
is more important than that in this case.

Abstracted "read directory" functions in SendMail and moved them
to Instructor. The instructor calls WeBWorK::Utils::readDirectory
and then filters the output according to a pattern match. Sorts as well.
Also move read_scoring_file to instructor since it will need to be used
in other scripts as well.

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

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.
