Wiring Upgrade

Continues the wiring upgrade. Now cameras, airlocks, robots, and air alarms also use the new wire datum system. Global wiring code is now removed but there are sneaky objects which didn't rely on them such as mulebots and autolathes. These will be converted separately.

Fixes a few issues from the previous upgrade.

Bonus material that came with doing a full port:
AI is now notified when a borg:
* Is slaved to it
* Selects/changes module.
* Changes name.

From a player perspective not not will change with the exception of one thing. Everything using wire-datums supports using signalers, it's no longer mostly restricted to airlocks.
As such one can now prepare an APC to lose power at an opportune moment later or setup a camera to disable itself to distract the AI and security elsewhere after you're long gone. 
There are other interesting ways to utilize this but I leave that up to imaginative people to find out on their own.

Or should this be:
```// blind_message (optional) is what blind people will hear```
