Fallback to OpenGL 2.0 on Windows if 3.0 is not supported
Additional verification that a Sampler applied to an effect is the correct type (CUBE with cube, 2D with 2D)
Added ability to set wrapR when loading a sampler via Material Properties.
Merge branch 'next' of git://github.com/blackberry/GamePlay into helpful-additions-textureCube

Conflicts:

Made sure Texture::createCube generates mipmaps prior to OpenGL 3.0
