Greatly optimize safe gear handling

- Safe inventory arrays are no longer sent over network to all machines
on server startup and on each lock/unlock
- Disabled user input then closed gear dialog during safe
lock/unlock/pack to block various duping methods.
- Moved safe creation, deletion and gear handling to server. This cuts
down on add[Magazine/Weapon/Backpack]Cargo, createVehicle and
deleteVehicle BE logs.
