instead of custom travis hooks

the geventwebsocket module (used by several backends) do use
collections.OrderedDict which is not available in python 2.6.
Thanksfully, there is a bw compat module available on pypi (ordereddict).

in chaussette/backend/_tornado.py and examples

in the source distribution (python setup.py sdist)

and fix the quick start section of the README file accordingly.

seems dead, see https://github.com/badges/pypipins/issues/37

Used to fail since tornado.wsgi.WSGIApplication inherits from
tornado.web.Application.

- add a *quick start* section documenting how to run the example applications,
- fix several URLs (travis, coveralls),
- remove links to https://pypip.in (seems dead).

- rename examples/tornado_app/tornadoapp.py to examples/tornado.py
- add comments on ho to use the different options
- add a wsgi app and a HTTPServer in the example
- add a small flask-based example, as an example of pure WSGI application
  that can be started with (almost) all backends.

Gevent monkey patching must happen early to avoid "Exception KeyError in module threading" errors on shutdown

Adding --graceful-timeout argument, allowing gevent based backends to respond to existing connections before shutting down

Update THANKS.rst

Add tornado backend.

It puts egg file to current directory.
The egg prevents `pip install coverage`
