Core/Vehicles&Movement:

- Send correct SMSG_MONSTER_MOVE with newly discovered SPLINEFLAG_EXIT_VEHICLE on vehicle exit. Fixes the "stuck on exit" bug as a result of removing the previous hack in 04b656a44f.
- Use SMSG_SPLINE_MOVE_ROOT and SMSG_SPLINE_MOVE_UNROOT as root packets for creatures.
- Reimplement toggling of MOVEMENTFLAG_ROOT on root event (including enter vehicle)
- Speedup in fetching movementflags for vehicles depending on vehicleflags on object updates.
- Code cleanup and refactoring
