Fix gaps between lines in HTML export in Chrome/Firefox on Ubuntu

Browse Source 
This is dependent on the font.
In both Chrome/Firefox, monospace uses "DejaVu Sans Mono" on my system,
but if I specify "DejaVu Sans Mono" explicitly, it uses a larger
font size (16px, as compared to 12px in Firefox or 13px in Chrome), and
slight gaps are visible.

This fixes a regression when switching over to the Rich API's built-in
HTML exporting — from where I'm sitting — but it may look totally
different on someone else's computer.
