CORS and authentication does not work properly

[rhuss]

When using CORS and authentication there are two issues:

• The client library doesn't set the withCredentials XHR Field to true
• The agent doesn't respond with a Access-Control-Allow-Credentials header.

See this article for details.

I pushed some changes, unfortunately I cannot test it with the provided fabric instatallation in #101 because I don't know to repackage (tried it naiively , but didn't work).

You need to update the agent (in fabric) and the javascript lib in hawtio.

I pushed a snapshot to our repository (should be there shortly). The JavaScript agent can be found here.

Could please someone give it a try ?

Tested it, looks good.
