Cleans up computer code severely. fixes issue #1004. Aliens and Monkeys can now smash computers. However, this only applies to computers with buildable circuit boards. Computers without boards are now impervious to attack and deconstruction(can't steal atmos computers or slash up the escape shuttle computer).

Hologram computer has been moved to unused. It has some interesting ideas, but it needs sprites and fix up.
Forgot that one of the computers had changed some icon names. Heres the dmi i forgot.
Modified DME that excludes hologram computers.
Merge branch 'master' of https://github.com/tgstation/-tg-station into computers
Reverts an accidental change to hydroponics.dm
Adds a toy AI to the arcade machine prize list. When you press it it'll annouce a random Ion Law to everyone around. This has a cooldown to prevent spammage and to make sure that the switch hell that is AI ion law code isn't taxing things too much (it looks a lot worse than it actually runs).

This replaces the blink toy in arcade machines, because they were a terrible booby prizes that no one in their right mind would mistake for something threatening because who in their right mind would leave a syndicate summoning beacon lying around instead of the thing that it summons.
Procs out Ion law generation
Adds a traitor item ToyAI that can upload the last ion law it generated via an upload console. Note that this is NOT a normal ToyAI that has been emagged, but rather an upload board mimicing a ToyAI (with a tell in the description).

This ToyAI has been added to the AI subversion bundle, note that since a traitor with this bundle already gets a hacked AI module there's no added benifit to it being there, its just for whimsical traitors who'd enjoy adding a little spice to the AI or false flag the changes as a badmin ioning an AI.
