Customize Button Select Mode

[ErinStepowski]

Add the ability to the Button widget to customize the Selected state. There are a lot of use cases where a user is opening a view that doesn't link outside of the application so knowing what button has been selected in a menu would be extremely beneficial.

Example of functionality would be like the below screenshot. The button links to a view that controls the content where the Near Me header is. Would be more user friendly to have the ability to allow shading indicating which view is active. Views Navigation widget does not allow for much visual customization and is not a viable workaround for these EBs.
