x11/dmenu2: Fork of dmenu with many enhancements and additional options

dmenu2 is the fork of original dmenu -- an efficient dynamic menu for
X11, patched to support features like flexible positioning, fuzzy
matching, follow focus, tab navigation, background dimming, etc.

This is a resurrection of a previously removed port following the
submitter's new upstream.
