Issue 150 For Windows OS

[ktonegawa]

An attempt to address https://github.com/david-cattermole/mayaMatchMoveSolver/issues/150 on the Windows end.

These changes attempts to address two things:

• The issue of Visual Studio defaulting to source MinGW as its main C++ compiler
• The issue of rcc not being found when coming to the part where it builds the UI/Documentation sections (I believe these are the relevant parts)

Initially addressed notes from @david-cattermole from this commit: https://github.com/ktonegawa/mayaMatchMoveSolver/commit/8f14a4241ebcee6478b1df90e9f874db814158b0

I also added a scripts/build_mmSolver_windows64_maya2016_extension2.bat so that users who may be using Maya 2016 Extenstion 2 (2016.5) like myself can build this plugin smoothly.

Thanks @ktonegawa those commits look good to me.

I expect the rcc fix will work on other platforms, or I will fix it for MacOS. The "ignore paths for MinGW" fix is only needed on Windows, so this commit fixes that :)

Thanks!
