You are now allowed to SK within one second after the spawn if you have at least one detpack in the world or are throwing a detpack. Previously, the anti-selfmax feature would block the SK because you would be maxed.
Fixed skillboosted players not being able to change class within one second before the spawn if they were already dead.
Mapmakers can now use the "setteamallow" key on trigger_once, trigger_multiple, and target_relay. If it has this key set to 1 or 2 and targets a door, then that door will only have its teamallow property set when it's used by the trigger/relay. For example, you can now have a 100% locked door that nobody can access, and then it can be hacked so that it is still locked but now allows passage for one team.
Mapmakers can now use the "justopen" key on trigger_once, trigger_multiple, and target_relay. If it has this key set and targets a locked door, then that door will just open once instead of unlocking (like the Ambush Room door at Cargo's first obj)
