[10145] Use better (but still hack) way for gameobject size calculation

* This is also hack because some float with unknown exactly value used as 'size'
* Another not resolved problem: go size used in creature target autoselection, so for large 'virtual' go
  creature can seelct strange points near in attempt select 'free' place near target.
