i18n: autodetect browser language

[andreslucena]

When I get to decidim.org I get the website on english. It should autodetect from my browser settings (catalan or spanish).

As far as I know it can be achieved from the hosting provider side. No coding needed. Just saying.

This could be done either by an .htaccess configuration or a small javascript. In any case, we'll need to set a cookie when the user selects a language, to ensure user preferences prevail. Also, I'd limit this to the home page, for now.

Thoughts @andreslucena ?

I have it working on #51 - the thing is that it doesn't allow to choose english on the homepage :(

There was an incompatiblity with this issue and #27 (regarding autodetecting browser language and changing lang on same page).

So i did some research. When the user changes the language, you can create a cookie called nf_lang or nf_country with the language/country code, and this will take presedence over browser language/ip based redirects. So in this case, selecting English should create an nf_lang=en cookie and on every other language change, you can simply delete the cookie.

hi @passatgt thanks for your contribution! I hope @andreslucena or @zuzust or @htmlboy can build from that.
