Allow creation of moment+langs.js

[wyantb]

Represents a continuation of #973 (didn't mean to create a new pull request specifically, but all the old work was made irrelevant anyway, and apparently github auto-closes pull requests if you delete the branch. Go figure).

moment+langs.js is a version of moment.js, prepackaged with all languages. Can specify --embed_languages=ar,br to create min/moment+customlangs.js with just those two languages (went with this over min/moment+ar+br.js since it was easier to configure; could switch over if that's still your wish). Also didn't indent the lang closures, since I think the file is readable as is; again, could indent if you guys want.

If you're wondering about lang/da.js, that was just a minor tweak so that it would match the replacement regex and pass jshint. And the error message is mostly in reference to lang/hr.js, which at this time has the old node-require instead of a UMD wrapper, giving example output of:

Warning: all language files must use the common UMD wrapper pattern. Failed language file: lang/hr.js

That looks pretty good, thanks for the effort!

Hi, i'm running:

grunt release --embed_languages=de,fr 

However, the moment-with-customlangs.min.js is not being generated.
The console gives me:

Destination min/moment-with-customlangs.min.js not written because src files were empty.

Hi @JobaDiniz

grunt release --embed_languages=de,fr

apparently should be

grunt release --embedLanguages=de,fr

@ichernev did anyone ever add documentation around the embedLanguages option? If so and I used the former, that seems to be incorrect. embed_languages seems to magically work with Grunt 0.4.0 (I'm not sure how) but only embedLanguages works with Grunt 0.4.5.

I believe we didn't add proper docs about that. We need to do it. I have to read grunt docs to figure the right capitalization.

@wyantb thanks man! It worked. :D
