[INDENT]render changes

IMaterial/CMaterial can now use ShaderConstant values to set variables.

IRender now maintains DesiredTechnique and is exposed publicly through IRender ( prior static use CShader::PushDesiredTechnique / Pop ). Similarly to before if a material has a technique defined this functionality is ignored.

IRender LookupShaderConstant function added to lookup render specific constant strings by ShaderConstant and vice versa. -- all functions return true if valid, input variables poll/convert are untouched if functions return false. ( CRender implementation in CShaderConstant.cpp )

IShader added inline function SetValueTexture( int iIndex, ITexture* ) which calls SetValueTexture( ShaderConstant::TEXTURE0 + iIndex ) ( matches IMaterials SetTexture(int, ITexture*) )
