toLocaleString is not fully implemented in many environments

[jsmreese]

Number#toLocaleString is not fully implemented in many environments, including IE10, IE11, Android, and others.

The moment duration format plugin should test the functionality of Number#toLocaleString before using it. And should employ a fallback version that implements those options used by the plugin.

See #68 and #69.

@mikeevstropov can you take a look at https://github.com/andyearnshaw/Intl.js
I think that if you were to add this lib to your project, everything might just work.

I'll check it out myself, but it might be a couple weeks before I'm able to.

@darkbluesun @mikeevstropov I've pushed a version of the plugin with a working fallback format function to the polyfill branch.

Using BrowserStack, all tests pass on IE 9 and 10, and Android 2.3, 4.4, and 6 in various browsers. Well, all tests except for two floating-point rounding errors when using the fallback format function (#93).

Please give this version a shot if you have a chance. I need to updated the documentation (may be a few days) before I publish the new version.

This fixes the behaviour in my app in IE10 👍

Thank you for testing @darkbluesun!

Pushed a new version to the polyfill branch that uses string-based rounding to fix #93 and #94 when using the fallback format function.

Ironically, IE11, Edge, and Windows Phone don't need to use the fallback format function, but they show those same floating point rounding errors when using toLocaleString. Gotta love JavaScript sometimes!

I still need to update the docs before publishing the new version.

Just published version 2.2.0 with the fallback function.
