[new] Add emblem.js v0.3.8

I'm not the author, but the npm package seems to be kept up-to-date by the author.

I am having some trouble following the documentation for npm or git autoupdate. For auto-updating, is there some command I have to run to fetch files to be added to the git repo? I've run into this issue with both the git `autoupdate` config and the `npm` config. Here's the error message I get when running `npm test`:

    emblem 
      ✗ emblem: filename from package.json exists 
        » ./ajax/libs/emblem/0.3.8/dist/emblem.min.js does not exist but is referenced in package.json! // valid-packages-test.js:100

Suggestions?
