* Moved enter/exit vehicle packets to spline.
* Fixed spline movement on transports such as elevators (for which we do not keep track of its exact position) - path will be using normal coordinates (not transport offsets)
* Implemented creature movement on transports
* Set minimum speed for creature allowed to start movement (too low speed leads to overflows in movement time calculations which in turn leads to crashes)
Spline movement controls movements of server-side controlled units (monster movement, taxi movement, etc).
Proper implementation of effects such as charge, jump, cyclic movement will rely on it.
However, need improve our states system before.
Technical changes:
* Added linear, catmullrom and bezier3 splines which based on client's algorthims. They can be reused for proper transport position interpolation.
* Precission increased. There are no more position desync issues since client's position calculation formulas used.
* Now possible to move by paths with multiple points, send whole path to client.

Original port for Trinity (ref #4629) Chaplain and Venugh
With the following incremental fixes during my review:
- Restore flightmaster end grid pre-loading
- Fix uninitialized Creature::m_path_id
- Add missing trinity_string entries for .movegens command
- Fix a bug in WaypointMovementGenerator that would trigger unexpected pausing at waypoints for various amounts of time
Known issues:
- Errors like WaypointMovementGenerator::LoadPath creature XXX (Entry: YYYYY GUID: ZZZZZZ) doesn't have waypoint path id: 0.
This is caused by bad DB data. This commit didn't "break" it.
Do not forget to re-run CMake before compiling.
