0030737: Visualization - implementing new selection schemes in context

AIS_SelectionScheme enumeration is defined to set which selection behaviour is used in Select of context
AIS_InteractiveContext is corrected to use single Select method instead of combination of Select/ShiftSelect methods with a selection scheme parameter.
Upgrade: Select() -> SelectDetected/Rectangle/Polygon(AIS_SelectionScheme_Replace), ShiftSelect -> SelectDetected/Rectangle/Polygon(AIS_SelectionScheme_XOR)
