Software Público Brasileiro

 - Added notifications for Organizations;
    - Only the profile admin can create them;
    - show_only_in_homepage option here works with profile homepage;
 - Rename plugin to be more consistent with new features;
    - Old plugin folder still exists, so old users can
      switch automatically when migrating;
    - If you want to start using it, activate "admin_notifications" plugin
      instead of "environment_notification"
 - Adds plugin namespace to tables, classes and modules;
