Trouble in Terrorist Town Update 4.1

There was going to be something for detectives and stab-proof vests in this update, but it doesn't seem that great considering it's yet another passive.

This is also probably the last update for TTT until after GM13 is released.

• The automated help messages are now gold and will appear every 2:30 instead of every five minutes.
• Added convar bb_ttt_showrandommessages to disable help messages (1 by default, 0 is off).
• Fixed a bug where Platinum users would no longer get their extended push bar.
• Fixed a bug where Platinum users would eventually gain an unlimited boost with prop pushing.
• If a player is killed within 10 seconds of round start by an innocent, all sub admins and above are notified.
