CustomStage Renaming Part 1

Search and replace:
GrCustomStage->GrEffect
GrCustomStageTestFactory->GrEffectTestFactory

renamed the cpp/h files from customStage->effect

reordered gypi, #includes, forward decls to maintain alphabetical sort.

manually fixed up some whitespace and linewraps

deleted a commented out #include
