* Highlight matching text in the active session when the text in the search bar changes,
  match case, match regexp options work as well.
* Ensure that newly created session views are given the focus
* Remember visibility of search bar for each session and hide/show the bar as appropriate
  when switching between sessions.
* Fix incorrect use of delete[] in emulation ( memory allocated with malloc() , so free() must be used )
* Treat empty regular expressions as non-matching in RegExpFilter ( fix infinite recursion )
* Prevent overdrawing of adjacent hotspots 
* Added some experimental / non-working code to do with scrolling in the displays
  This breaks the scroll-bar and causes crashes at the moment.  It needs
  to be re-worked.
