Reined back over-use of virtual functions in GHOST, especially in "leaves" of the inheritance hierarchy. This eliminates vtables for many classes and (in some places) turns virtual function dispatch into direct function calls. I'll be around to fix things if other coders think this change is too much. Still lots of virtual in GHOST_TaskbarWin32 since it just loves virtual.
