With bug 889335 fixed, we can stop listening to mozSettings' changes to language.current and use the new window.onlanguagechange event.

What do you think Stas?

I thought the patch would look exactly like this, but upon testing it turned out that the languagechange event was emitted twice: the first time navigator.language was en-US, and the second time it had the new desired value.

Here's what I see when I change the language from en-US to fr (not shown here, but I also tested navigator.language, just to be sure it's the same as the first value of navigator.languages; it was):

E/GeckoConsole( 1073): […] in l10n_langchange: navigator.languages: en-US, en
E/GeckoConsole( 1073): […] in l10n_langchange: navigator.languages: fr, en-US, en

Interestingly, here's what I see when I then change the language again, this time from fr to zh-TW:

E/GeckoConsole( 1073): […] in l10n_langchange: navigator.languages: en-US, en
E/GeckoConsole( 1073): […] in l10n_langchange: navigator.languages: zh-TW, en-US, en

Not sure why it says "en-US, en" again on the first line.

I got curious and dug into Gecko a little bit to see why the event was emitted twice.  Consequently, I filed and then fixed bug 1016038.  Changing my f- to f+ as the patch should work correctly now.  Let's just fix the typo before landing, please :)

As per https://groups.google.com/d/msg/mozilla.dev.gaia/LSL5d3EOPAM/_Gtmc-B1DWgJ, this will be useful for apps migrating away from being certified.  Gandalf, do you want to land this today?
