Change order of default monospace fonts, remove Terminus

Having a bitmap font as first choice is really stupid, as noted
by @Evropi in #322 (this fixes #322)

As Inconsolata is a wonderful font that has the advantages of
a monospace font combined with a level of readability that is
otherwise reserved to sans-serif fonts, I think it should be first
in the list.
