Implemented PocketPC menubar/toolbar as wxToolMenuBar derived

from wxToolBar, solving the problem of how normal toolbars
can co-exist with combined ones. Tidied up WinCE toolbar code.
Implemented wxToolBar as 'dummy' toolbar under Smartphone.
Dialogs now show an empty menubar to hide inactive one
underneath.
