Huge Smaxx patch with some fixes by me:
- support for non power of two textures
- modelview matrix calculation optimizations
- health effect when picking up health crates or using vampirism
- rc plane training time trial
- fix visual gear drawing position (might require recheck)
- gamepad support
- reordered options in frontend
- updated binding options (subcaptions, descriptions and localizable names)
- cfg-dir parameter for frontend (allows teams/settings to sit on a usb flash drive for example)
- icons for chatroom user list
