fix typo in database.conf.dist
Fix typo in Config.pm

fix type in datbase.conf.dist
Add hack protecting against the possibility that userProblem doesn't exist (none was assigned?)
Add bugfixes from Geoff Goehle to ProblemGrader.pm
Add drag and drop facility for installing languages.

Move a lang.po or lang.mo file to the Localize folder
(defined in defaults.config but set to lib/WeBWorK/Localize by default).

The name of the file will immediately appear in the General/Langauge
section of the Course Configuration page but it won't be possible
to switch to that language until an apache server restart has occurred.

Apparently mod_perl processes and stores the .po and .mo files so they
are not read on the fly.  Can this be changed?
