Slate changes: Allowed hyperlink decorator and hyperlink run to be more easily derived from by moving some functions/variables to protected. Added new run & decorator for hyperlinks in tutorials that add an icon to the end of the run if required. Only use icon-style run if in display mode (not in edit mode). reviewed by Jamie.Dale [CL 2322460 by Thomas Sarkanen in Main branch]
