This is going to replace the sticker grid for those people with Javascript disabled.

This way it is easier to find the sticker to use, see some info about the sticker and it not suck like it does now.

So the sticker grid will be going away in the future and replaced with a link to this page.

If you have JS enabled, there will be no changes except you can go to /stickers to see all the stickers on a page.
