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.

Reverts an accidental change to hydroponics.dm
Makes circuits into type paths. Dna modifiers had a bad string that showed up when converted into a type path. Power monitors are now actually computers. Makes smashing computers red.
Fixes camera computers. Also, stops runtiming cameras. Fixes issue #1352. If a camera or computer is broken it prints the location to the runtime log, and then either continues, or gives up(in the case of a bad computer).
