Title: Remove Opera sniff

SUP BEN.

Opera 9.64 is like, 9 versions old. I know Ryan has a fork that normalizes its old document.postMessage implementation--but I think that's going to help like 0.01% of all Opera users. So....this is easier and won't break any sites or provide a crappy fallback for current Opera users.
