Possible disappearing plants fix

Hopefully this will at least tell us what is wrong when plants disappear when they're supposed to load a new model.

Smoother scenario handling

Really just a minor bugfix for being able to ninja out of a car using a weed seed.
Re-did the whole process of starting a scenario so hopefully people won't get stuck in them and it can't be exploited to jump from cars.

Burning

This version adds some item checking and compatibility.
Mainly, though, it adds a burning effect for when you destroy plants.
