1. Derive wxMessageDialogBase from wxDialog (why did we use multiple

inheritance here?), moved more wxMessageDialog fields into the base class
2. Added functions to set the text of message box buttons (patch 1700393,
   currently only implemented for wxMac)
3. Added wxMessageDialog::SetMessage() and SetExtendedMessage() and
   implemented them for wxMac (part of the patch), wxGTK 2.4+ and in
   a generic way for everybody else
4. Allow changing the dialog attributes between creating and showing it,
   for this the real dialog creation is now done on in ShowModal() in all
   ports

+Notice that this function is not currently available on all platforms, so it
+may return \false to indicate that the labels couldn't be changed. If it
+returns \true (currently only under wxMac), the labels were set successfully.
+Typically, if the function was used successfully, the main dialog message may

+\helpref{SetMessage}{wxmessagedialogsetmessage}. If it is set, the main message
+appears highlighted -- if supported -- and this message appears beneath it in
+normal font. On the platforms which don't support extended messages, it is
+simply appended to the normal message with a new line separating them.
