Fixes #145: on iOS5 view does not have rounded corners when using pattern image as background color
Post SVProgressHUDDidReceiveTouchEventNotification when touching overlayView and maskType isn't none.
Merge branch 'master' of github.com:samvermette/SVProgressHUD
Post notification on UIControlEventTouchDown instead of touch up.
Don't set object in NSNotification.
