Updating script support, taking requests

[Thomas]

Bit vague and not very technical, but the ability to spawn monsters and allow them to patrol without their patrolling music playing, but with the soundtrack of that room playing. For example.

10_amb is playing, but a monster spawns. 10_amb is still playing but dan_grunt doesn't.

I think this is already possible by making a new ent file for the monster where the ambient music is empty ("").
