0031987: Visualization - Slow rectangular selection on models with big number of sensitives

Browse Source 
SelectMgr_SensitiveEntitySet now stores a map of registered owners with a counter of registered entities.
SelectMgr_ViewerSelector::traverseObject() now reads the number of sensitive entities for specific owner
from SelectMgr_SensitiveEntitySet instead of re-computing it every time.
