add new badge for course settings lti tool

Fixes RD-79

test plan:
 - add an lti app with the course_settings_sub_navigation
   extension (probably have to modify the xml for an existing
   app).
 - go to the course settings page and see the app shows up at
   the top of the right sidebar.
 - on the console, change the integration_type for the tool to
  'lor'.
 - refresh the course settings page and see the app now has a
   new badge.
