Need a way to catch undo/redo (and cancel) in WebKit

HTML editing libraries at Google need a way to catch undo/redo (besides just
listening for the DOM mutation events) so that they can keep internal state
relating to the document, beyond just the HTML.  Without being able to catch
these mutating events (and ideally canceling them!) WebKit just smashes over
the DOM and the HTML editing libraries have to clean up after it.

HTML5 has some nascent undo/redo apis:

but we're going to need something a bit more full featured in the future.
