I'm not a webui guru, but this is probably unnecessary, since it's done by an
~initializer in browser_options_profile_list.js  (and if it _was_ necessary the
profileIsSupervised clause would be broken :).

Done.

Does this need an accessor (i.e. trailing underscore => "private")? (It's also
@private, and I think dbeam's working on running all this through closure)
