Quickie code contribution: EXPLAIN queries in profiler.

Well there you go, thats how lazy I am. Hurray for overriding the class. Shame its still kind of a monkeypatch of quoted HTML, but what can you do.

S'worth pointing out too that I've only tested this on MySQL variants; while I know SQLite & Postgre both support EXPLAIN syntax, I'm pretty sure MS and oracle have their own annoying method, in which case, hey, this'll break. I should probably poll it for a known SQL-92 adherent, but like I said, lazy.
