Workaround for issue #692.

Pull request for this workaround intended to fix the [issue #692] (https://github.com/angular-translate/angular-translate/issues/692). Tested under latest chrome (37.0.2062.102 m) + [https everywhere extension] (https://www.eff.org/https-everywhere) and latest firefox (31.0) and the same extension. The example code now works as expected under this browser/extension combination.

I tried to maintain all dependencies local since it was originally in that way, but this particular style file didn't work as expected. That's why.
So do you prefer to convert all "library" file links to cdn instead of local? Let me know please.
