Patch applied with the following changes:
- Moved all deps to $PGASRC/../pgadmin3-deps/ on Windows.
- Replaced the wxTreeCtrl with a ctlTree (which draws lines properly on
GTK), and added the appropriate XRC resource handlers.
There is a slightly odd effect with the text box on dlgAddFavourite and
the wxTextEntry dialogue on Windows in which the cursor keeps returning
to immediately before char 4 (even if the textbox is actually empty),
but it does actually work as expected.
Andreas; can you look at that please? I'm somewhat baffled...
