Humans/AI shell cannot change borg cells in the docking station

[Roomba]

I can see why borgs might be unable to change their own cells, but there's no reason borgs can't change each other's cells if the AI shell can (although not at the moment due to this bug).

Really though, if roundstart/transformed borgs started with a 15k power cell instead of a 7.5k one, it would solve a ton of cell-related issues.
