*Movement Generators standardization.

- bool GetDestination(&x,&y,&z) added to all movement generators.(it is used by update of players view distance)
- Fixed when creature entering in combat not count this as StoppedByPlayer.
- Random Movement Generator - added support for creating custom spawndist during the game.
- Random Movement Generator - Db spawndist is checked only at initialize(NOT in each sellect of random location).
- Added Random Movement to motion master - it can be called now by MoveRandom(spawndist) e.g. for use in SD2.
- Home and Random movements no more using RespawnCoords(Home Position has implemented)
- Fixed bug when creature is moving on path and enter combat, after that returns to spawn position.
-Typo fix in Confused Movement Generator
