Styling of buttons within a BaseMetroDialog should be facilitated

[pfattisc]

Is your feature request related to a problem? Please describe.
With MahApps 1.6.0 (Fix Dialogs Resource handling #3142) it is possible to easily customize the BaseMetroDialog Style.
But to restyle the buttons within a dialog (MessageDialog, etc) it is still necessary to use the MetroDialogSettings.CustomResourceDictionary.

Describe the solution you'd like
I think the button styles AccentedDialogSquareButton and AccentedDialogHighlightedSquareButton from the BaseMetroDialog.xaml should be moved to Controls.Buttons.xaml.
This should do the trick so I can overwrite those resources globally (and only once!) in app.xaml.
