Subject: [PATCH] Add an option which defines the lineheight

Despite both the panel and dmenu using the same font (a Terminus 12),
dmenu is shorter and the panel is visible from under the dmenu bar.
The appearance can be even more distracting when using similar colors
for background and selections. With the option added by this patch,
dmenu can be launched with a '-h 24', thus completely covering the panel.
