Cleanup phase 1

+ Added XendoMod update notice and removed original WepSpell one.
+ Added locatization support for newly added XendoMod class.
+ Added XendoMod overview tab in Admin panel (currently unpopulated).
+ Added BF3 and TS3 Servers in Database.
* Changed all external calls to match the new class-system.
* Fixed some error introduced by faulty merging. Index page was corrupted, is now fixed.
* Changed installer to support custom XendoMod database entries and general setup.
* Pages 1 and 2 are the welcome page and the media-gallery respectively. This is now hardcoded! Dummies added to DB.
	Content in DB does not get overwritten if already in place. But ids 1&2 are unusable so any content in there would need to be moved to another id.
* Changed stats-template to fitt default webspell theme.

Todo:
- Add config of XM's default config while installing/upgrading.
- Localize menus etc.
- Add features.
- Replace WebSpell's deprecated methods with their current equlvalents.
