Updated map version to 0.7.3

You must be using the experimental branch of Teardown for this version.

Adjusted some code in the ceiling fan scripts, in the police station. The fans will now slow down to a stop when damaged or when the main breaker is off.

-The radio tower's light in Classic now flashes like a real tower beacon.

-Rotated some antennas throughout the map towards the tower.

-Added more detail to the tower.

The platform ride and scrambler controls in Fairgrounds have been upgraded to levers.

Added 2 towers to the Classic map. The taller one exists in Classic and Villa, while the smaller one is taken from Realms and now exists in Classic as well.

- Small changes to object and joint positions throughout the apartment building.

Surprise! More Villa changes/additions.

Also, the big yellow steel racks behind the factory are now props. Heavy props at that.

More additions to the Villa's garage.

Small fixes to the Villa map - fixed some joint and object positions.
