Fixed major bug when using Titanium dialog

Error on previous version: Presenting action sheet clipped by its
superview. Some controls might not respond to touches. On iPhone try
-[UIActionSheet showFromTabBar:] or -[UIActionSheet showFromToolbar:]
instead of -[UIActionSheet showInView:]

Fixed by adding in removing from superview and tested working with
3.0.2.GA and added in compiled version.
