Track URIs based on which URIs are in the JSON coverage data.

In hybrid mode the server cannot track which javascript files have been
served. We gleam which have been served based on which files we got
coverage data for in the JSON data from the post request.
Autoload jscoverage.js in hybrid mode

jscoverage.js is automatically loaded from the JSCover server via cross
domain script whenever a instrumented javascript is loaded by the
browser. This only happens in hybrid mode.
Send coverage automatically

Coverage will be sent back to the JSCover server automatically upon
unload of the data by the browser. This only affects hybrid mode.
