[10086] Implement use .go command with shiftlinks or player name.

* Now if for .go command provided no X Y Z args command will not teleport player to nowhere.
* Instead command allow used with player name and work as simplifed .goname
  (teleport to player _point_ in user instance binding, not to player instance)
* Also command can be used with diferent point coordinates provided shift-links:
  - player (result for example .lookup player account)
  - creature (result .list creature command)
  - gameobject (result .list object command)
  - tele (result .lookup tele)
  - taxinode (result .lookup taxinode)
