I added the reflective Shader into the TR folder.

I tested it and fixed a bug with the 1.2.2, as they don't like to load multiple shaders from one file.

the Shader has the internal name of "ShaderNG/TR_Reflective_Emissive_Alpha" so this has to be used in the config file for WindowShine

Changelog:
the Shader should now work under Linux&MacOS
