Gives the AI a simple hud

And removes a bunch of verbs. Buttons on the hud are:

* Jump to core (covers two removed verbs because #4026)
* Camera list
* Track
* Camera light
* Crew monitor
* Crew manifest
* Alerts
* Announcement
* Call shuttle
* State laws
* Send message
* Show received messages
* Take picture
* Show pictures

That I have biasedly chose as the most used and gave some QUALITY icons.

Here's how it looks like, CHECK OUT HOW EMPTY IS THE VERB WINDOW.

Oh, and also fixes a HORRIBLE BUG WHERE DEAD COULD COMMUNICATE WITH THE LIVING because dead AIs could toggle camera lights. I'm not even (completely) joking, people communicated by ~rotating chairs~...
Usr is fine here because it's HUD stuff. Things directly accessible to the player (verbs, Topic()) are often safe to use usr in. 

Also, I guess you could put these two lines in their own proc and return usr if it's an AI but then you'd still have two lines because you'd want to check if the proc returned anything at all.
