provide better visuals to differentiate scope of classes, methods, and properties

[davidhabib]

currently, one must expand the method list to see the full method signature. It would be nice if in the collapsed state, the method name bars had some sort of visual to indicate scope.

we could potentially do something similar in the class menu. I currently am just using color of the class (blue = global, black = public, gray = private).

scope is displayed on all signatures, and dynamic scope filtering allows you to show/hide different scopes. So I think this is lower priority.
