- Allow changing OGLES2 shader in SIrrCreationParameters instead of using the IRR_OGLES2_SHADER_PATH define.
- CGOLES2Driver::createMaterialRenderers() no longer crashes on missing shaders but just prints out warnings.
- Fix some minor memory-leaks in CGOLES2Driver::createMaterialRenderers() (was using delete instead of delete[])
- Rewrite CGOLES2Driver::createMaterialRenderers() to avoid redundant code
- Irrlichtify variable names in CGOLES2Driver::createMaterialRenderers() (local variables are lower-case!)
