WinRTCompiler fails to build in VS2013 about angleproject

[josh-coronalabs]

Additional Note:
I used to be able to build the old glslPrecompiler.exe in Visual Studio 2013 just fine with the changes I've mentioned in issue #3 (link below) and adding preprocessor definitions COMPILE_SHADER, USE_FEATURE_LEVEL_9_1, and ANGLE_ENABLE_D3D11.
#3

But that said, I merely tested if that glslPrecompiler was able to convert/compile shader language into byte code. I did not verify if the compiled shader actually worked.

Should have an updated VS2013 project for you on Wednesday.
