Made exact/max size setting more robust.
Gallery filter now deletes affected caches when defaults change.

Used coder to try to clean up code standard (except for the G2 camelCase of
course). A painful exercise! Hopefully I didn't break anything.

and used the hack in #121306 to do the same for the Gallery2 admin sitebar
(off by default).
- Fixed up the handling of exactsize and maxsize.
- Added form validation for sizes (and sidebar settings).
- (Hopefully) fixed small bug in filter where n param was ignored.

- task: added exactsize option for search
- feature: simple report generator (to assist with bug reports)
- bugfix: support for piped arguments in filter tags
- bugfix: several issues with 'Site Admin' group <> 'admin' role sync feature
- bugfix: add code to handle admin user (uid=1) properly after install
- many minor bugfixes

- task: rework of G2 filter code
- feature: simple regexp for language codes
- many small bugfixes and cleanup

- improved user/role sync (incl. batch import/export of users)
- tabbed configuration screens
- better debugging options
- gallery_menu module (link to G2 albums from the menu)

 again once the correct methods to import module css files has been documented
 (see http://drupal.org/node/60096).
 - The css file is now not included twice on gallery pages (is correctly loaded
   after Gallery2's theme.css file and so can override)
 - This *removes* the functionality to use a theme specific drupal_g2.css file.
   There have got to be better ways to override module css files.
 - css improvements to not hide h2's in G2 Admin pages
 - Removed DOS line endings from gallery_filter.inc
