Grants Silicons the ability to hack bots! [Port from /tg/][Poll in progress]

A silicon (AI, cyborgs) is now able to hack any robot through that robot's interface.

A hacked robot behaves mostly as an emagged one does.

Hacked robots cannot be deactivated via interface. *If it was manually emagged, it cannot be stopped except by destruction.* If a silicon hacked the bot, it must be reset by a silicon before it can be shut down.

Manually emagged robots cannot be restored by silicons. They must be destroyed instead.

The following robots are affected:
- Medibots (including Mysterious versions)
- Securitron
- ED-209 (including laser tag versions!)
- Floorbot
- Cleanbot

This is adapted from the /tg/ version, but more-or-less the same code! Poll link below!
