0026147: Visualization - restore the ability to pick only fully included objects in rectangular selection

2 modes of rectangular selection are available: inclusion-only and overlap-allowing;
The modes can be switched using method AllowOverlapDetection from StdSelect_ViewerSelector3d;
BVH for sensitive entities now builds if there is more than max number of leafs in collection;
Added option -allowoverlap to command vselect;
Interactive rectangular selection in Draw is now available in 2 modes:
- if the user starts selection from upper corners, only fully included objects will be selected;
- if the user starts selection from lower corners, both partially and fully overlapped objects will be selected.
