begin implementing new control reference

Goals:
* re-write control reference based on jQuery
* should run as a normal web page and as a chrome app
* when running as chrome app, connect to DCS-BIOS and show live data
fix defineRockerSwitch(): set max_value=2 in documentation
implement #16: auto-sync feature

This change will periodically retransmit every value regardless of
whether it has changed or not. This ensures that a new client that
has connected to the export data stream after the aircraft has been
initialized will be up-to-date within about 10 seconds.
speed up control reference, add live data view as chrome app

Use jQuery instead of angular.js for the Control Reference.
When running as a Chrome App, the reference docs will try to connect
to DCS-BIOS (on the same computer) and display live data.
