Subject: [PATCH] Add colors to status message in bar.

This patch matches the format used by
https://dwm.suckless.org/patches/statuscolors/ -- An \x01 character
switches to the normal foreground/color combo, \x02 switches to the
color combo used for selected tags, \03 is set by default to black on
yellow, \04 is white on red.

These color settings are defined in the colors array in config.def.h.
More can be added, but don't have more than 32, or you'll start hitting
real ASCII.

This applies cleanly on mainline dwm from commit 022d076 (Sat Jan 7
17:21:29 2017 +0100) until at least b69c870 (Sat Jun 2 17:15:42 2018
+020).
