v0.2.0

Update examples, with new base uwsgi-nginx image that starts a dynamic number of processes from 2 to 16 to handle uWSGI responses.

That's specially useful in cases where there are some slow requests that take time to respond, allowing all the other fast requests to be answered quickly (in a different process) without having to wait for the first slow request to finish.

Also, there's now support for Python 3.5. With an equivalent image tag in Python 3.5 for each standard image tag and an equivalent example project template for each image tag. Nevertheless, Python 2.7 is still the default, as is for the Flask developers.
