1. Might we want to remove the RunEndure method for now since it's not in use?

2. If we do keep it, and we know we want it to be the same as RunWebrtc, then
maybe it should just call RunWebrtc?

def RunEndure(self, action_runner):
  self.RunWebrtc(action_runner)

Yeah, I double-checked and nobody calls RunEndure anymore, so I'll just throw
those away.

I'm not very familiar what with this now, but if it fits the pattern used by
other page sets, then it's OK I think.

[phoglund_chromium, 2014/09/25 11:31:58]

I copied it from another page set, so I think so.

     self.AddPage(Page2(self))
