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

- 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
