Make and use a meta-editor script

Many programs handle EDITOR and VISUAL differently, so this it's
always uniform (if EDITOR is respected, anyway): Terminal capabilities
are tested to see whether the dumb editor should be used or not.
Additionally an X11 editor can be set and will be used if possible.
