Avoid duplicating base class DoSetSelection() implementation in wxTreebook, just extend it slightly by using DoGetNonNullPage() to allow using a (sub-)page if the page associated to the selected item is null and reuse it. Also get rid of wxTreebook::m_actualSelection, it seems completely unnecessary to bother keeping and updating it when we can just find it whenever we need (which actually seems to only have been the case in the now removed DoSetSelection() implementation anyhow). As a side effect of this, wxTreebook pages should now be sizer correctly when switching to them as DoSetSelection() in the base class does call SetSize() on the page before showing it, unlike the previously used version in wxTreebook, which omitted this call for some reason. There should be no other user-visible changes. Closes #4379.
