Re-Added wxStream::StreamSize()

Added in-place editting to wxTreeCtrl,
    modified wxListCtrl in-place editting
  Corrected behaviour of wxToolBar::Toggle() to not
    send messages and to report the correct state
  Removed many #include "wx/wx.h" to speed up
   compilation
 Some more compile fixes and tests.
