Made changes here so that it's in line with the other templates. I've not been
able to verify this page visually as I'm not sure when this page is displayed.
The guest session on CrOS does not allow you to open an incognito window, only
new guest tabs.

[Evan Stade, 2014/04/22 17:52:52]

You should ping someone (altimofeev looks like a good candidate) to figure out
how to trigger guest incognito, or if it doesn't exist any more rip this code
out.

Confirmed with the Moscow team that this is still required. This enterprise and
guest section is currently not triggered which they discovered is a bug.  

New bug has been filed, which I will fix separately in a new CL.
