Removed UI autorotation support, since UIImagePickerController doe not gracefully handle being showin in non-portrait orientation and there is not at the moment a supported way to force the UI into a specified orientation. git-svn-id: https://zxing.googlecode.com/svn/trunk@595 59b500cc-1b3d-0410-9834-0bbf25fbcc57
