Mattes D 6492aa000b Merge pull request #909 from jfhumann/fixes 
Bug fixes and optimizations.

We need to visit the API functions and check that they return only those values expected. `cWorld::CreateProjectile()` seems affected, too, by the same issue of ToLua returning extra values. In the cleanest form, these functions will need moving to ManualBindings.cpp
