Patrol heli, bradley, satellite crash sites get saved correctly instead of all crates disappearing when the server restarts
- Enable saving on all of the crates and server gibs, the OnFire state persists
- Converted satellite crates to the same LockedByEntCrate setup that heli and bradley use, got rid of TimedUnlootableCrate
- Set all of the crate despawn time to 30 minutes from 60 (doesn't make sense for them to stick around longer than the gibs)
- Fix heli crates landing on unloadable train wagons again (needed an extra fix now that they're saved)
