Icon update (as if you care).

I discovered potterpuffs and potterpuff_fans recently, and I just had to filch a particular icon (credit has been given where due). And then decided that as long as I was at it, I'd fiddle with a few others. The Palpatine one was a last minute thing; it was originally just going to read "lol" or similar, but I thought of the Firefly ref and suddenly couldn't resist. If you think it would work better the other way (considering a) I've already got a Firefly icon and b) some people might not get the reference), let me know.
