MSCO 2.10.1: car doors and garage door synced, door lock fix, perf tools

- Car doors (FSM with bool "Open" and "Open door"/"Close door") are synced as open/closed:
  the receiver removes the hold joint and frees the hinge, closing runs the game's own logic
- Fix: every synced close of an already closed Satsuma door added another FixedJoint, so the
  door could not be opened anymore; extra joints are removed automatically
- Hinge sync also covers world doors/gates with hinges (garage door), interaction by bounds
- Scene name read once per frame (Application.loadedLevelName allocates a string per call)
- Console "perf" (FPS, ms per MSCO part incl. OnGUI, GC, hook calls), -msco-perf start option
- Console "fsmdump <text>" / -msco-dump: PlayMaker FSMs and hinges to MSCO\fsmdump.txt
