Title: Add ability to set parent view opacity when presenting semi modal view.

When presenting the SemiModalView, it use to fade the parent view to 50% opacity
(fixed). Add methods to set the opacity level which will make it more flexible
for displaying other content in front of the view (e.g. text).

Change is backward compatible (i.e. does not break existing code) and requires
user to set property on view. Implemented using objective-c runtime set/get
Associative Object Behaviors on the view controller instance.
