Illuminator for Loomen by Covac

Changes a background color of newly added courses to Loomen(currently only the one hosted by Carnet). Since there is no functionality provided by Carnet or Looment that tracks or provides information on new courses this addon stores old course's id and marks them with date it colored so that the next time you open you can see highlighted courses more easily. There is also a feature in options to change color that applies immediately and saves it for later.
