Fix camera preview orientation
Change preview size to 640x480
Change the default values contrass, sharpness and saturation (use the values from the original camera driver from the froyo leak)
Restore some functions removed when porting to CM10.1 - keep them and make compiling instead of removing
Merge pull request #4 from Dorregaray/b10.1
