UI Nits: Mac and QT5 Toolbar

Fixed up to make the toolbar on a build on QT5 look a little
more like one on QT4 where they still have unified toolbar
and title support.

We should look at managing via the native NSToolbar in the
near future since Digia have made it clear that they are not
keen to reintroduce unified toolbars in QT5.
