Title: Allow data URLs and the img 'alt' attribute.

This should fix #455. But I'm not super happy w/ the monkeypatching
approach I'm taking here, similar to my fix for #32. Might want to
eventually push this kind of configuration upstream to bleach too.

(This is almost the exact same code as #460, it's just been rebased instead of merged in an attempt to make commit history cleaner... Sort of an experiment, I guess.)
