Silicon Medical and Security HUDs!

- The AI can now access both Security and Medical HUDs via a new button
on its UI. The Medical HUD is exactly equal to all others. The AI's
Security HUD cannot detect implants.

- Cyborg HUD modules have been removed in favor of an inbuilt command,
to make it less of a hassle to access them.

- HUD code has been given its own file such that it can be used by any
mob. In addition, HUD users are placed into a list instead of searching
for only humans and checking them for a HUD item. This is to make it
easier to expand.

- Security HUD messages can now be received by any mob using a SecHUD.
RR's tweak + derpfix

Makes the sensor augmentation check for silicon instead of one for both
the AI and Borgs, since they are not actually different procs.

Reverts an accidental removal of the borg camera function, thinking it
came from NT's code.
Nerfs to AI's HUDs

- AI Medical HUDs require that the person's suit sensors be enabled (any
active mode) in order to view status data.

- AI Security HUDs display only the person's job as given by their ID,
no security status or implant detection.
