bemenu: add --line-height / -H option

Text is displayed vertically centered in a line. If unspecified, or 0,
the previous behaviour of making the height the size of the text, plus
two pixels on either side, is used, so there will be no change in
behaviour if this option is not used.

Fixes https://github.com/Cloudef/bemenu/issues/44.
