Add normalizer so we can escape user email address
Remove controls/copy for unimplemented features

  Things we haven't implemented yet:
  * Resend verification email
  * Cancel verification email
  * Delete account
Lots of small fixes

  * wire up unverified panel
  * remove references to removed, unimplemented DOM
  * escape user's email before we show it, just in case
  * fix model scope inside panel by changing variable name slightly
  * pass email to panel sections, so they can show it
  * cancel click event bubbling/default behavior, just in case
Implement most of the FxaPanel tests
