Fix: elevator and door instances don't reference Revolution

What it says in the title. Elevators should work now:tm:, and doors aren't broken anymore. Loads of invalid instance names are fixed.

Oh, and I removed the portal spawners with missing models, I assume they referred to a Revolution model.

Leave it to Valve to hide what looks like half of a testing level inside two soundscape instances
