ColorMatrix for Vapoursynth

So I've finished the initial porting of ColorMatrix to Vapoursynth. It can be downloaded here. Source code is on Github here. It seems to work fine on the few test clips I tried but I can't say I tested it fully so let me know if you stumble upon any issues. There is still further cleanup and removal of Windows dependencies to finish up, but this should be enough to at least test.

Parameters are the same as the original ColorMatrix the only difference is that the bool values have been replaced with ints (0 for false and 1 for true for anyone who is unfamiliar).

Usage:

>>> import vapoursynth as vs
>>> core = vs.Core()
>>> core.std.LoadPlugin('/path/to/ColorMatrix.dll')

And minimum needed to call it:

>>> ret = core.colormatrix.ColorMatrix(clip)
