New "shim" Network Access Manager, new 'browsermode' example and more.

The new Network Access Manager currently is designed to do just logging:
- logs HTTP Method type
- logs HTTP Destination URL

The new 'browsermode':
It's in "/examples" and make PhantomJS do just a call to "open(url)".
It has a companion shell script to help with the task.

Also, improvement for Message Handler:
messages are now prefixed with ISO Datetime.
