1.5, added stuff, fixed stuff

- mod icon
- fixes for new vanilla clipping issues
- GenClosest optimization improving repairing, wardening, tending jobs
- caching for new ListerBuildings methods
- DynamicDrawManager single threading
- Type.GetFields caching
- StatParts analyzer category
- removed duplicate steam warning and optionally window
- added exception handling for debug menu, incidentworker, Graphic_Multi, InitializeComps, making all those now log what mod broke and not cause black screens or whatever
