rework _handle_selection()

Browse source 
* do not use timer for selection, due to issue with Engine.time_scale == 0
  * deciding on redraw based on target cell change
  * deciding on send to system based on mouse button up event
  * remove _on_selection_held() timer callback function and SelectionMode enum
* on non-Linux system use clipbord when copy_on_selection is active
