tests for $.fetch

[dperrymorrow]

We need tests for $.fetch, have had a few of issues reported around this method #111 #127 #128 #91 , and its difficult to begin making changes without tests in place.

a good testing strategy would be to use sinon.server

I created a simple template for testing $.fetch.

For now it's just echoing the request data back to the client. However, we have to discuss whether #128 is still a valid bug though. Should we improve the way data is stringified?

I can write more tests for fetch once we figure out all bits and pieces!

@LeaVerou I think the hook-commit broke fetch.
xhr => env.xhr?

Line 98: this[name] = hooks[name] || [];
hooks is undefined.

Argh. On it, thanks for spotting!
