LibGUI: Make descendants of AbstractView define their own select_all() (#1201)

Browse source 
AbstractView does not know which column it's displaying which makes it
impossible to implement the select_all functionality up there. Now
descendants override the pure virtual select_all method and implement
it themselves.
