efm - add a rfecent files menu (up to 30) wirth minimal mime icons

efm now tracks the most recent 30 files opened with timestamps in
100th of a second and a menu with these recent files under
main menu -> navigate ... the icons are plain mime type icons and not
thumbnails as the efm code isnmt really usafle to create icons in
menus without a lot of work. something to keep in mind for the redo of
efm... :)

at least you can easily access recently opened files with efm now :)
