Urban Terror 4.1 Scope Removal - Add r_ScopeRemoval to cvars - RE_RegisterShader in tr_shader.c - Written in 2012

/* 
====================
RE_RegisterShader

This is the exported shader entry point for the rest of the system
It will always return an index that will be valid.

This should really only be used for explicit shaders, because there is no
way to ask for different implicit lighting modes (vertex, lightmap, etc)
