Drone Improvements - Take 2 PR Boogaloo

1.
Drone storage slots are identical to human ones, all functionality should be possible now - Thanks JJ!
2.
Clicking a drone shell pops up an alert to the player, rather than immediately making them a drone.
The alert informs the player they lose their chance at cloning.
3.
Drones now have a Hat/Mask slot which can equip any Hat or Mask type item. - Thanks JJ!
4.
There is now an Admin spawn syndicate drone which spawns with an uplink and a syndicate hardsuit helmet on it's head. This drone has NO bad items allowing it to pick up anything - Thanks JJ!
5.
There is now a Drone Ping verb, it alerts all drones to the user's location with an alert of the user's choosing from Low, Medium, High or Critical. (This feature may be swapped for a Drone Radio channel, Feedback is being gathered)

Drone bad items list has been removed, the Admin policy is good enough now.
