Adds the driver for the Princeton Instruments USB camera.

Needs a lot of work...

TODO:
	- make checkpatch.pl clean
	- coding style fixups (typedefs, etc.)
	- get it to build properly
	- audit ioctls
	- remove ioctls if possible
	- assign proper minor number
	- remove dbg() macro
	- lots of general cleanups
	- review locking
