Add initial implementation of AutoFill++. This implementation is hidden behind a switch, --enable-new-autofill. So far, we only pop up an infobar asking the user if he'd like to save the form information. I've added a rudimentary icon for the infobar, pulled from the mocks, so we'll probably want a blessed version of this icon at some point.

BUG=18201
TEST=none
