NOTE: this is mostly just formal adding 2 movegens with very limited cleanups.
Real result from adding 2 new movegens possible after apply more deep cleanups/fixes
in UNIT_STAT_CHASE/UNIT_STAT_FOLLOW set. But this will need more cereful changes
because we have currently sometime strange dependences and places for set for this flags.
Similar cleanups required for other movegen related flags. Infact i have related patches but
need more testing before apply step by step.
To update a creatures distance to it's target without creating a new movement generator. Note it can only be used where creature is using TargetedMovementGenerator.

Implemented delayed movement generators removed in case cleanup is triggered
from movement generator update. For this purpose is in runtime allocated vector
for temporary store of all deleted movement generators. After delayed delete
this vector is deleted.
