People are use to using .has()? It was only just added - at the same
time as .contains() as well.
I'll mull over the .contains() discrepancy. I may just punt it and
push people towards .has() anyway.
Looking at .has() now I'm not 100% sure why it's filtering and not
just returning a boolean, like .is(). Hmm. If .has() returns a boolean
then yeah, consider .contains() gone (and a jQuery.contains will be
provided for those that need a lightweight method).
