    [dmenu][patch][highlight] Add revised patch
    
    This commit adds a minorly revised version of the original highlight
    patch by Miles Alan. This revision introduces a new array element in
    *colors[SchemeLast][2], called [SchemeOutHighlight], which sets the
    foreground and background colours for matched text in multiple selection
    mode (previously missing in the original patch), along with necessary
    changes to dmenu.c. This patch has been tested and applies cleanly to
    the master branch of dmenu.
