Allow themes to override [NSMenu _isVisible] (#307)

Browse source 
The default implementation of `[NSMenu]` uses `_aWindow` and `_bWindow` to determine the visibility of the menu.  Not all themes use these windows to build a menu.  For example, the WinUXTheme will use Win32 APIs to build a menu.

Allow themes to override the value of `[NSMenu _isVisible]` by introducing a `[GSTheme proposedVisibility: (BOOL)visible forMenu: (NSMenu *) menu]` method.  The default implementation simply eturns the proposed visibility.
