Simplify selection
Update the selection buffer and file in-place: - Append file path when one is added. - Remember the last position in selection buffer at which the next filename is to be appended when a directory/context change happens (lastappendpos). So in case of a de-selection we can go back to that position and scan all the entries to add only the ones which are selected.
