Orbital Survey Plus

- M700 now shows altitude parameters for scanning the current main body
- IndexOutOfBounds exception spam around north pole has been dealt with
- Scan area "squishing" mitigation around polar regions improved
- Shrunk saved scan data in persistence file (still rather heinous but better), old saves should be ok
- "Time Between Scans" applies to active vessels also (it's not scanning every tick anymore)
- Added "enable background scan" setting
- Quick check to make sure everything works fine in 1.1.1
