0029262: Visualization - AIS_InteractiveContext::Load() does not register Object...

AIS_InteractiveContext::Load() now loads the object regardless specified selection mode and decomposition flag.
AIS_InteractiveContext::Load() and ::KeepTemporary() now register object in the Viewer
in the same way as ::Display() does.

Draw Harness command vdisplay has been extended with new flag -erased to load object into context in erased state.
