Updated unoccupied sync to be more flexible
Updated unoccupied sync to be more flexible

There are now different distance thresholds for different vehicle types.
Heavier vehicles like trucks and planes are harder to move but boats and
bikes are easier (boats were also changed mainly to work well with water
sync).

Also added a 10 second delay to a vehicle being used so it doesn't get
frozen as soon as someone jumps out.
