Removed redundant proxy class Prs3d_Presentation - Graphic3d_Structure now should be used directly. Removed auxiliary class PrsMgr_ModedPresentation holding Structure and Display Mode index (field has been moved to Structure itself), so that PrsMgr_Presentations (AIS_InteractiveObject::Presentations()) now holds Structures directly. PrsMgr_Prs proxy class has been removed, and PrsMgr_Presentation now inherits Graphic3d_Structure. Graphic3d_Structure, maps declarations have been corrected to use class instead of void*, which allowed to avoid redundant casts. Several methods have been also modified to avoid creating Handle from this pointer. AIS package headers have been cleaned up from forward declaration of Prs3d_Presentation class. Fixed dereference of destroyed presentations within connected and HLR computed objects: - AIS_InteractiveContext::Disconnect() now erases connected presentation. - Graphic3d_CView::Clear() now removes destructed structures from Computed list. - fix inaccessibility of PrsMgr_Presentation methods
