pagekite: Fix issue with setting port

- When the current configuration does not contain a port and we try to
  set the port for the frontend server, it fails.  This patch fixes
  that.

- Minor styling and spelling fixes.

- Make sure that if port is not set for frontend, it will be set on
  saving the form.
