Language detection + linking

[snostorm]

I think our i18n efforts are far enough along now we should be linking to them and possibly suggesting to users they hit those pages versus english.

I'll propose something simple in a PR for this. Just tracking the idea here.

Sounds good. Are the loaclization teams still hosting on country specific domains? If so, I think we should heavily encourage them to use cc.iojs.org, if not require it for maintaining a repo on github.com/iojs.

Discussed in the last meeting, a some sort of non-url language selection should be priority over (and should come before) this.

Saw this in the learnyounode repo and I think keeping links like the ones on top is a good idea: http://www.finnpauls.de/learnyounode/guide/hello_world.html

@julianduque thanks. We probably have too many languages now to go horizontal, but I'm thinking of ripping of Wikipedia and going vertical at first. A dropdown is an option too, but is less obvious. (Also, long term, not every article may exist for every language, so this might help with per-article translation discoverability.)

If we could us Unicode flags or something that would be rad.

@Fishrock123 No, please. Flags/countries != languages.

[Fishrock123]

Flags/countries != languages

Ah true.

We could add automatic redirection to the localized version based on the user's 'Accept-Language' header settings. There's an nginx module for that: http://wiki.nginx.org/AcceptLanguageModule
