Translate text rather than having it in code directly.
Makes tickets_controller a bit less complex.
Users now have an email_address, not an email.
More minor cleanup of tickets controller
Link to users show page rather than edit, now that we have a show view for users.
Edit form should show email address for the currently displayed user.
Use ticket_url to get URL for unauthenticated ticket creation, and only flash that message if the ticket already has a flash[:message] (and thus was saved successfully)
