User guide:
http://wiki.blender.org/index.php/Dev:Source/GameEngine/Fisheye_Dome_Camera

Fixed two bugs from original patch:
- deleting a text will clear the warp field from Game framing settings
- removed spurious black dots along the edge of the cube map in the gameplayer 

Known limitation:
- resizing of the screen doesn't work in the gameplayer

Known bugs:
- Texture with reflexion are not rendered correctly
- Spurious problems with light
