Update to match current server

I've updated the consumer to work with the current server and more specifically the n2k data started with `bin/n2k-from-file`.

The consumer is very intolerant of missing data. For example the nme0183-signalk parse is pretty incomplete in terms of supported sentences and GPGLL ( Geographic Position, Latitude / Longitude and time) in the data file used by bin/nmea-from-file does not get translated, you get a tree without position data and the error caused by the missing data kills the UI updates.

I've assumed that bower components are available under /bower_components/ and React is loaded from there.
