WebcamJamUpdate()

I have re-written some major parts of the JamCam app. The differences on the outside are so slight that I decided not to bother launching it again. I've just over written the first one (below).
I have added some keyboard functionality:
SPACE: Change video mode (Cam, Colour Transform, Grid)
UP/DOWN: Contrast
LEFT/RIGHT:Brightness

I will be releasing source soon. I have to go to work now.

That is all. :)
