blender/source/gameengine/Ketsji/KX_SceneActuator.cpp
Campbell Barton 22b501c791 fixes for bugs submitted by BGE users, fixes by myself and Mitchell Stokes 
- when the attribute check function failed it didnt set an error raising a SystemError instead
- Rasterizer.getMaterialMode would never return KX_BLENDER_MULTITEX_MATERIAL
- PropertySensor value attribute checking function was always returning a fail.
- Vertex Self Shadow python script didnt update for meshes with modifiers.
