Sets starting Heat to 5 on all smaller Multiplayer jobs on all difficulties (this includes Art Of The Heist but excludes Rendezvous, 1st mission in Secret Symphony, Golf With The Dragon and Payback, due to their own separate heat scripting that I haven't figured out yet).

Side effect: Dragon Dogs starting Heat is 4 due to it's unique setup.

Note: Possibly causes semi-random crash issues for clients who don't have it, so best to host private lobbies with friends who also have it.
