Sortable Fusions

[Solumin]

Allow the user to select how the fusions should be sorted:

• By name (of output)
• By attack
• By defense

Default sort would be by attack, I think.

I added isotope on my branch. It works well enough at first but it's...not great for sorting elements that didn't exist on page load (i.e., everything that we want to sort). It also does some weird things to the DOM. We might want to look at a different sorting library or make our own sorting functions.
