Do not change behavior of UIButton

Hi, 

Remember I showed you strange behaviour of UIActionSheet? I finally found it. `UIButton (ExtendedHit)` is thing that overrides UIButton hit area in all elements :(

You can take a look at this issue demo [here](https://github.com/yury/PBJVision/blob/broken_uiactionsheetview_example) just clone it, checkout broken_uiactionsheetview_example branch and run.
