Include various helper js and css files if developermode is on. Also, include the packed MochiKit file if developermode is NOT on, to speed things up quite a bit

Ignore files in the theme/ directory, only look through directories. Make sure to throw a proper exception if a problem occurs getting the theme list also.

Added 'developermode' flag, with comment about what it's for (developers\!). Should provide a reasonable performance boost when not enabled.

Added a note. When the site language is set to something that is not english, and a user registers, the language they see is english, because the default for people when it's not set is NOT 'site default', but 'en.utf8'. This needs fixing in the UI for account settings as well, there is already a bug for it.

Bugfix: take the user's language into account when setting the language of tinymce/calendar/pieforms stuff

Added german language file for tinymce (there's still some more tinymce language files for german required though)

Renamed a language string to prevent confusion with another string named the same, but that has a different translation

Fix to have pieforms use the language the site is using. Added german translation of expiry element (thanks to Heinz)

This reverts commit 035ebd5d.

Upgrade to remove group tables from Mahara. They'll be back, as renamed community tables, but for now, farewell! *plays taps*

Fix issue found when attempting to upgrade a dupe of myportfolio.ac.nz - lang setting might already be fixed in the database, causing a foreign key violation
