Allow access rules to include in site configs

[mightydok]

Hello.
I want to add support for custom access config files, like:

allow from 123.123.123.123
deny from all

I cant use nginx_configs section, because this type of config will be autoloaded at nginx restart and can broke access to web server, so i think i must add another section like nginx_auth_basic_files.
I change role, README and travis files.

Hello @mightydok ,
Thanks for the pull request.
I am more in flavor to use ansible templating.
You have examples here:
https://github.com/jdauphant/ansible-role-nginx/releases/tag/v1.2
and more details here : #33

What do you think ?

@jdauphant i think example with access rule, with just simple allow all; will suit.
