Kinda bummed that we have to paste this code everywhere that we create a tab
with kChromeUINewTabURL. Are these two files the only places? Can we catch it
elsewhere, perhaps in one of the browser_* files?

well, this is translating calls that were to content to be instead to other code
in chrome, so I prefer if you want that changed, that's another cl. i just want
to clean out the content interfaces at this point
