Database improperly closed in example code

os.unlink(flaskr.DATABASE) causes the actual application database to be
purged; whereas, I reckon, one wants the _test_ database to be removed.
So every time I ran it, the test passed, but ended up crashing the live
app for want of a valid database.

I avoided using the sample code in examples/flaskr thus far, as I chose
to type out code from the turorial docs. The actual example code looks
good - at least to my beginner's eye.
Updated jquery.rst with the current Google Developer hosted libraries URL and jquery version
Added self to AUTHORS file
fixing process_response

Flask.process_response will throw away functions is receives from ctx._after_request_functions if there is a Blueprint that has used @after_request
Update README

No need to manually initialize the database with a call to `init_db()` as this call is done before `app.run()` in flaskr.py, when you run the file.
