Masonry support for collections

[peiche]

Per the last point on the wish list, I've added a masonry option ("yes" or "no") to the Collection component screen and shortcode.

[aesop_collection title="Hello" collection="1" columns="3" splash="off" masonry="yes"]

A couple things need some attention, though. Firstly, the description of the masonry option. I don't know what to put there, so you guys can worry about that. ;) Second, right now the masonry lib is always loaded. It should probably be conditional. (The ASE-specific script is always loaded too, but it's concatenated into ai-core.min.js. This will throw an error if the masonry lib isn't loaded, so I leave that decision to you guys.)

Cheers!

Thanks so much for the work that you have done. People like you help Open Source Projects to continue to thrive.

This could be a great addition, however, I think it may need some refactoring before it could be merged, such as the aforementioned conditional loading of masonry.js. Also, the component CSS files have all been changed. What did you do there? It just appears like they aren't minified.

I don't think they were changed, save for collection.less. I think they're just what resulted from running grunt less.

I agree that some refactoring needs to happen, but I wanted to at least get some of the larger pieces in place.
