-Added 64bit support, sprites should display correctly now when running PrisonArchitect64.exe

Added Paint Cabin where cars in a Large Garage will be painted into a different colour. Already existing large garages won't have this transparent roof, but the cars on the two topright spots will get a paintjob anyway.

- little cosmetic fix: when the Gantry Crane of a large garage finished putting an engine in a Lesson Car it would sometimes go back on the wrong side of the lane to park the hook.
- for some unknown reason a repaired car would sometimes not be aligned correctly on the road but placed against the wall next to it. The limo driver would then not be able to navigate to his car so he would stay on top of the map. Solution would be to remove the indoor wall where the car is put back on the road. The driver would then start walking down again to fetch his car. I've adjusted the code a bit so the hook will now always spawn the car on the x position of the road and his own y position, instead of his known current x/y positions. I guess this should fix it, but this issue happens only very rarely and is hard to reproduce, so you'll have to see for yourself.

Oops, forgot to add the new crane booth to the dismantle button on the rail, fixed. :)

- Car Mechanic Helper will now operate the Gantry Crane at a control booth to give him something more to do.
- Limo Driver will spawn on top of the road to drive away with his repaired car.
- Added some more entity sprites for mechanic and limo driver.
- Completely broken engines get refurbished at the lesson car and put into the parts rack.


THIS VERSION IS INCOMPATIBLE WITH INITIAL RELEASE
You will need to dismantle the crane (use Delete button on a Crane Rail) and bulldoze the room, then place a quickbuild room again.
