Remove slash from FallbackResource

Apache config is not my thing, so this might not be correct. However, what I can tell is that it does not work with the slash for me, and that it does without the slash.

s/middlewares/middleware

Feel free to discard this PR,
but reading 'Middlewares' with an 's' feels jarring to me,
I never saw it written this way before.

For uses without the 's' see :
http://english.stackexchange.com/questions/257120/middleware-vs-middlewares
https://en.wikipedia.org/wiki/Middleware
http://expressjs.com/guide/using-middleware.html

I did find uses of 'middlewares' in these pages, so, again, feel free to discard :
http://guides.rubyonrails.org/rails_on_rack.html
https://blog.engineyard.com/2015/understanding-rack-apps-and-middleware

But for example it appears just twice with an 's' in this stack overflow page, and many more times without the 's' :

Fix env variable in travis.yaml

SYMFONY_DEPS_VERSION=3 was never evaluated correctly as the before_scripts are comparing with 3.0
The tests were still installing 3.0, as minimumStability=dev, but maybe it is nice fixing that.

Replace binary gender examples with something that is actually single-choice

In order to include people who do not fit into the gender binary, gender fields really should be a free-form text field. As such, this patch changes the `choices` example to use a billing plan instead.
