We are shipping a custom style that uses "Ubuntu" instead of "Droid
Sans", thus there is no need to download the "Droid Sans" font
from Google's CDN.
This change should improve explorer's loading time in the situations
where the external URL takes too long to load or cannot be loaded at
all, for example when running behind a restricting proxy.
Previously, highlighting classes were being added to the DOM but had no CSS
so the user just saw black - a lot of CPU usage for nothing.
These styles now attractively and minimally style resposes so long as
they are below a certain threshold, as well as model schemas.
The highlightSizeThreshold fixes the long hang users would
see when large responses were returned.
