Profession traits

One thing I could do to make professions meaningful.

- [x] Thoughts on the character-screen color for a professional trait would be appreciated.
     As per usual, no response to a direct ask.  Went with white.
- [x] Cop and doc traits implemented.  Still would like to grant computer access, but overhauling terminal-handling seems like a good way to de-Stablize things, and that's a bad idea right now.

Canceling the jock line as I'd like to get these in for the new stable.

Plenty of room for further thought in these, too.  Let's hear it!
