fixing dev mat reload on keyup events. Fixes DEVELOPER-862
Partial fix for DEVELOPER-832

This fixes things on our end. Things like microsites (which I think
we're going to be reworking anyway), quickstarts, and ticketmonster
(basically anything that uses markdown or asciidoc) are not fixed, and
honestly I'm not sure of a good solution for those yet.
