MacViews: Gets wrench menu working

MacViews: Gets wrench menu working

WrenchMenuModel was set up differently between Mac and Views at compile
time. This change unifies the model so that the wrench menu can work with
MacViews.

Use ButtonMenuItemModel as submodels for Cut/Copy/Paste and
Zoom/Fullscreen menu buttons. Update Views menu to work with this model
change.
