[Pythoncard-users] resourceEditor - widget ordering

When you hide/show a windows/control in wxPython 2.3.x it changes the
ordering of the controls on the panel. This behavior is a side-effect, but
as long as it is available, I decided to exploit it.

The widgets for a PythonCard app are in a 'components' list in the .rsrc.py
file for an app. The first widget in the list will always be in front of the
second item, which will always be in front of the third item, and so on.
This is the only control we have over tab order and layering that I know of
until more options are added to the underlying capabilities of
wxWindows/wxPython.

So, to take advantage of this I changed the resourceEditor, so that when you
add a new widget using the Edit menu, all of the widgets are hidden and then
reshown so that the new widget is the first item in the list and appears in
front of the other widgets.

I'll experiment later with the logic necessary to change the widget ordering
so we can have menu items for:
  Send to Back
  Move Backward
  Move Forward
  Bring to Front

The source for the resourceEditor is turning into a messy hack job almost as
bad as the Property Editor, but I think I will continue to glue on features
before doing a complete rewrite. I would still appreciate suggestions, bug
reports, etc. Once the menu dialog is added it should be okay for building
non-sizer layouts from scratch even for a newbie.
