0028801: Visualization, Select3D_SensitivePrimitiveArray - add option to keep index map of detected elements

Browse Source 
Select3D_SensitiveGroup - added option to force overlap check for all entities in the group.
Added interface for accessing last detected entity in the group.

Select3D_SensitivePrimitiveArray - added option to keep index map of detected elements
and option to split array into groups for faster initialization of extra-large arrays.

BVH_Geometry, BVH_Object - added missing accessor ::IsDirty() for checking BVH tree state.
