jsbridge 3.0

Python to JavaScript bridge interface

[jsbridge](https://github.com/mozilla/mozmill/tree/master/jsbridge) is a python-javascript bridge interface for Firefox and Mozilla applications.

jsbridge works as an [extension](https://github.com/mozilla/mozmill/tree/master/jsbridge/jsbridge/extension) loaded into Firefox or Thunderbird (etc.) that opens a socket, by default on port 24242, that is used to mirror data structures between python-land and JavaScript-land The python component opens the same port and communication takes place.

[JSObject](https://github.com/mozilla/mozmill/blob/master/jsbridge/jsbridge/jsobjects.py)s (jsbridge.jsbobject:JSObject) may be used to mirror objects across between python and JavaScript.

jsbridge is utilized by [Mozmill](https://developer.mozilla.org/en/Mozmill) as part of its testing infrastructure.
