Added AboutUI page for connection-help.

Added an AboutUI page for chrome://connection-help, that displays a
subset of the information available at
support.google.com/chrome/answer/6098869. On a separate CL, logic
will be added to redirect users who visit the online help center and
get an interstitial to the chrome://connection-help site.
