Date formatting with safari

[benzen]

Doing this doesn't give always the same result on safari 8

When using the reactIntl mixin

let d = new Date();
d.setMonth(i);
this.formatDate(d, {month: 'long'})

On chrome it give me 'January' looks like normal.
On Safari it depends:
sometimes i see 'january 2015' and somother i see 'janury'.

Is this related to andyearnshaw/Intl.js#107

@benzen yeah, the polyfill has that particular issue. We are tracking that issue here: andyearnshaw/Intl.js#125
