Filing this as a follow-up to bug 869494 to keep track of landing the last patch in there only on fig. This way, we can just close bug 869494 when the first 3 patches land on m-c.

The last patch in bug 869494 is pretty bitrotten on fig now... I'm working on updating it now, and I can post it again for review before landing it on fig.

I had to do quite a bit of unbitrotting to get lucasr's patch to apply to fig. I built with the patch, and it seems to work okay enough to land on fig, but I'd appreciate a quick once-over to make sure I didn't make any big mistakes. Because of the HomePager changes, the parts of the patch to animate showing/hiding about:home didn't apply at all, so I just decided to put on those with FIXMEs that we can fix in follow-up bugs :) Same thing for implementing filterEditingMode (lucasr already had a FIXME for that in AboutHome, but I decided to make it an even higher level FIXME, since I'm not sure what API we want to be using for that with HomePager).

I decided this is good enough to land, we can fix things in follow-ups: https://hg.mozilla.org/projects/fig/rev/5d9bbd9db49f
