  (toggle_headercontextitem_filesize, toggle_headercontextitem_filetype,
   toggle_headercontextitem_datemodified, toggle_headercontextitem_showhidden):
  new functions toggling the related entry in the settings file and updating
  the visibility of the columns
  (headercontextmenu_requested): new function creating the header context menu;

* files-dock-widget.h: new functions toggle_headercontextitem_filesize,
  toggle_headercontextitem_filetype, toggle_headercontextitem_datemodified,
  toggle_headercontextitem_showhidden, and headercontextmenu_requested
