[dev] dmenu patch to return all matching items (for a new dmenu-powered music player interface)

Hello and thanks everyone.

As part of a project to create a simple and fast music player
interface, I patched dmenu to allow it to return all matching items
instead of just the one at the cursor. dmenu is the browsing
interface; and there is another mode of operation that takes keywords
as hints for a partial match on filenames. The items then get loaded
into a mpc/mpd playlist with a shell script. See
http://github.com/dbro/muss for that code.

Why is this patch of interest? I call it "filtermode" because it uses
dmenu to generate a list of matches, with interactivity similar to the
trendy "instant" style of searching. For applications working with
sets of items, this method could be faster than the existing
dmenu-multiselect patch, in that it doesn't require the user to
manually select each item they want. The basis for the patch is dmenu
v4.1.1 .

Suggestions, comments welcome.
