It appears we were shipping font files without license text, and I
had my doubts about the bitmap fonts being usable directly.
This replaces existing TTF fonts with Apache-2.0 licensed fonts from
chome core (Cousine, Arimo, Tinos). Include the full license file
for all three fonts.
The Lucida Sans font bitmap is removed entirely for non-freetype
builds. There is therefore only mono fonts for non-freetype builds.
