ENH: brought the code for CRSLtd. devices back into psychopy/hardware
Merge branch 'master' of https://github.com/psychopy/psychopy

Conflicts:
	psychopy/hardware/crs/bits.py
	psychopy/visual/window.py

Substantial conflicts, hopefully fixed

Also fixed test of PR655 on linux (was incorrectly 'finding' a device)
ENH: Added support for mono++ and color++ modes to BitsSharp

Moved support for these into psychopy rather than a separate lib for ease (and for esaier distribution)
