undoapi: made SfxUndoManager an implementation of the new, abstract ::svl::IUndoManager interface.

Change the SfxShell's UndoManager attribute to be an IUndoManager. Did all the resulting changes
up the source tree.
This way, we'll hopefully be able to provide an IUndoManager implementation in Writer, which
is not based on the SfxUndoManager, but on Writer's own Undo implementation.
