Add metadata and main field to package json

[wbinnssmith]

Since the jQuery plugin registry is no longer writable, and instead recommends publishing packages to npm, this adds all of the metadata from the localize.jquery.json file to the package.json including the "main" field pointing to the unminified build.

jquery was not added as a dependency as it is not explicitly required.

Would appreciate an npm publish when you're ready 😄

I've gone ahead and added the grunt build as an npm prepublish step and published this branch of jquery-localize to npm. Let me know your npm username and I'll add you as the owner!

Thanks, Will. I'm behind the times. :) I just registered on npm as coderifous.
