HUGE performance issue with large datasets

[musicin3d]

During initialization, you're running the filter() function after adding each list item. That filter function runs through the entire list of previously loaded items.

This is a BIG no-no. With 1000+ items, firefox grinds to a halt. In scientific terms, this is a time complexity of O(n^2). In less scientific terms, it's a CPU bomb.

Another PR is coming.

I'm managing a fork of this project and our version numbers are out of sync now. I don't have time to submit a proper PR right now. Here's a gist: https://gist.github.com/musicin3d/3e0d411bb90f4d7c576537f00057e039

Much better. Performance issues are reduced drastically. We have about 3000 items, took about 45 seconds to load. with this update it take 5 seconds.
Thank you.
