DarkRadiant ShaderLibrary

The ShaderLibrary holds all the named ShaderDefinitions and the named Shader objects.

The ShaderDefinition map gets populated during startup when the material files are parsed by the ShaderFileParser.

Shaders objects are instantiated on the heap (and kept track of by using boost::shared_ptrs) as soon as a request getShaderByName() is reaching the Doom3ShaderSystem class.
