Software Público Brasileiro

Changes:

    * Implemented require_ssl and refuse_ssl in ApplicationController
    * Changed AccountController to require SSL
      + pointing to HTTPS in login forms
    * Changed PublicController to refuse SSL, and fixed all controllers
      in app/controllers/public to inherit from it (with some
      exceptions).
    * Changed MyProfileController to require SSL

Side-effects:

    * Some controllers had been changed in an unappropriated way for the
      new SSL requirement.
    * Some tests changed to reflect the new SSL requirements.
    * Needed to tweak content_viewer controller to deal with SSL URL's:
      + Fixed detection of user coming from public view that was broke
        by the SSL thing.
    * adapted enterprise_registration tests
