Immersive Vehicles

Features:

Added variable-gravity to vehicles in the config.  Makes for more responsive car falling.

Wheels now use the lowest wheel for calculations.  Prevents tipping vehicles, and allows for hybrid powertrains, or lifted vehicles with IVV.

Custom type parts are now generic type parts.  Not much else changed about those.

Vehicles can now have multiple hitch/hookup points and types.  They can also mount one another.  Allows for things like flatbed vehicles.

Parts can now have hitch/hookup points.  Allows for convertible trucks that can either have a towing attachment or a pickup attachment.

Various improvements to ground logic.  Makes vehicles easier to control on the ground, and less likely to get stuck with half of them in the air.

Changes to gun code now allow for better pack-based gun control.  However, this comes at the cost of turret guns not rendering for packs for the moment.  Expect funky stuff for a few updates.  Guns will still fire in the proper direction, but they won't look like they are.

Fixes:

Finally fixed propeller aircraft with smaller propellers not having enough thrust.  Thanks Fsend!

Fixed scanner not picking up all the possible part locations.

Fixed brakes not disengaging when dismounting vehicles.  No more vehicles with constant red lights.

Trailers now disconnect when wrenched, rather than trying to go back to their vehicle when placed down again.

Fixed simpleThrottle not using the starter and instead just auto-starting.

Fixed door hitboxes not rotating with their part.

Fixed parking brake not being able to be set sometimes.

Fixed mirrored parts being offset in the wrong direction.

Fixed sub-parts that requested no mirroring actually being mirrored.

Fixed vehicles with shared textObjects crashing.

Generic parts now respect min/max rather than ignoring it.

Fixed item icons not appearing on modular pack formats.

Fixed part slot hitboxes not taking part rotation into account.

Fixed helis with auto-hover enabled overheating... only on the client.

Fixed effectors doing multiple effects.

Fixed cameras not working on parts.
