ENH: setupApp.py needed some extra hacking for opencv2 on mac

Unfortunately they hard-coded the locations of libs according to the
framework locations, but the app has them in different locations
we now create symlinks to the locations opencv2 expects (ugly!)
ENH: added HSV colorspace to Builder visual stimuli
TESTS: fixed test for the fact that hsv colors are now supported

I also removed spaces from the testing of components files (when
whitespace gets auto-stripped by an editor it results in confusing
errors in this test)
