More sanity checks to make sure clients aren't doing something they're not allowed to:

- AICharacter, hull, structure and submarine updates from clients are ignored
- character updates from anyone else than the client controlling the character are ignored
- players can't pick/drop items from anyone else's inventory (unless the target is unconscious/stunned/cuffed)
- server has authority over reactor temperature
