Alternative to dmenu_run adding command history

- drop-in replacement for dmenu_run, no dmenu patching necessary
- when doing multiselect, runs command immediately upon selection
- added note to the current 'history' patch pointing to this

+Note
+----
+
+As an alternative to the patch above, the following script is meant to replace
+`dmenu_run` : it handles the command history in a similar way as the patch and
+can be used with an unpatched dmenu 4.6.

+dmenu_run with command history
+==============================
+
+A self-contained alternative to dmenu_run which also handles history.
+
+History is saved in a file in `$XDG_CACHE_HOME`, with fallback to a dot
+file in `$HOME`. Change as necessary.
+
+In addition to the above, dmenu_run_history will launch each entry
+immediately on `Ctrl-Return` (multiselect).
+
+The script can be used with the 4.6 version of dmenu.
