UITextView: Allow tapping links from NSAttributedString, but disallow text selection

hack.m

/**
 Note to self:
 This UITextView class extension gets calles every time iOS wants to add a new gesture recognizer to the textView.
 It checks for the type of the gesture recognizer (Long Press) and then for the associated action.
 Only if the action is ``smallDelayRecognizer:``, the gestuere recognizer will stay enabled.
 All otheer long press gestures will be disabled.
 
 Purpose:
 Allow user interaction with the links in the attributedText, but disallow text selection
