Add error handling in ShaderProgramBuilder

[GoogleCodeExporter]

Shader building system should stop the building process, rollback all changes 
and report error, if an problem in the process raises. Instead, the build goes 
on mindlessly only reporting the problems in logs.

This has been partially addressed, the underlaying code is ready and things 
like this and build on the new shader model ideas.

New shader system uses the old ShaderProgramBuilder and there is no problem in 
an fallback to FFP. I choose to make this low priority.
