2.10.8: fewer hitches

- Sending on a background thread (the game thread blocked whenever the TCP
  buffer was full, e.g. while uploading the save); small frames are batched
- Server save requests: routine saves wait for a calm moment (not while driving
  fast) and are announced; urgent flag from server 2.10.5
- Dynamic built-in font for all MSCO GUI (Unity logged hundreds of
  "Font size and style overrides" warnings with stutters)
- Admin VEHICLE tab rescans every 30 s / after actions instead of every 5 s;
  time/weather FSM search less often
- Reused buffers for Build/Frame/Poll (less garbage, fewer GC pauses)
- Hitch log: GC and save detection, count of hitches between reports
- Show Bolt Size 1.0.1: finds the FPSCamera (Camera.main may be missing), uses
  MSCO's shared FSM list instead of FindObjectsOfType every 2 s
