Added wwapache2ctl and webwork2.komodoproject to .gitignore (the last is a project file generated by an IDE I'm trying out).
Sometimes users change user_id's. Given a course_id, an existing user_id in that course, and a different user_id, this script will (a) create a user for the new user_id if the account doesn't exist and (b) will also copy all existing data in the database associated with the old user_id to the new user_id. TODO: Currently copies all user set and problem data, but does not yet copy achievment data. We also want it to modify answer_log data so that the new user_id gets the same past answers.
Merge pull request #67 from dpvc/package_errors

Resolve "Can't locate package ... " errors for MathObjects like LimitedPolynomial
I think having the shebang line '/usr/bin/env perl' is more portable than /usr/bin/perl. It works on all *nix's and also allows for the script to work unmodified when a local administrator changes the perl path
Added code to back up existing answer_log and then replace old user_id with new user_id

CAS authentication module, associated conf file and changes to Login.pm and Logout.pm
Merge pull request #70 from aubreyja/master

CAS authentication module. Note, this has been well tested at UC Berkeley with their CAS system and verison of webwork.  More testing, especially with this dev code, would be welcome.
Added support for URLs as provided in WWfeedback messages

I had inadvertently provided an older version of CAS.pm when submitting
the original version.  This brings CAS.pm up to date.  The only change
was/is to add support to keep params on the URL being sent to the CAS server
(so that URLs provided by WWfeedback messages work properly).
Fixed copyright date, and minor code cleanup

Enable comma escaping, unicode chars in classlists

Classlists files as processed by the addcourse script can't deal with users
who, for one reason or another, has a comma in either their first or last
name. Using the Text::CSV module for CSV parsing instead of split() enables
comma escaping values by putting them in double quotes.

Users who have non-ASCII characters in their name gets their name (e.g.:
Frøystein) mangled after going through addcourse. This commit forces Perl
to open the the classlist file with UTF8 encoding. This way the unicode
characters survive intact into the database.

Remove LimitedPolynomials and Inequalities::common from the preloaded list (now that the package errors are resolved).  Must put back the original contextLimitedPolynomials.pl and contextInequalities.pl as well
