all ui frontend code is now in typescript. we no longer need jshint, and we build the frontend code during "make build". this also changes tlsrpt types for a Report, not encoding field names with dashes, but to keep them valid identifiers in javascript. this makes it more conveniently to work with in the frontend, and works around a sherpats limitation.
