Beacon and Chat Fix

- Fixed issue with setting broadcast range on beacons.  This should be
fixed, and /off will work along with setting broadcast radius in your
live entities list
- Fixed chat so that it's a textbox instead of a list box (you can copy
text out of it now!)
- Fixed player list so that it doesn't deselect the player selected, and
also replaced the steamid of the dedicatedserver with the name "server"
- Fixed it so that you can't kick or ban the server
