New API for extending the activity chooser and implementation of favouriting

Testing the callback deprecation Create a few preconfigured tools (admin > plugins > manage tools) and set to show up in the activity chooser. In mod/lti/lib.php, find the method 'lti_get_course_content_items' and rename it (just add a few random letter into the name so it won't be found). Now, go to a course as either the admin or a teacher. Turn on editing mode. Verify you see a debugging message on the page, telling you about the deprecated get_shortcuts callback. Now open the activity chooser Verify you see the preconfigured tools in the list of activities Click one Verify you are taken to the tool configuration page, allowing you to create the module instance. Testing a single activity format for modules with subtypes Make sure you have preconfigured tools set up and visible in the activity chooser. Create a new course Edit settings, and select single activity format. Wait for page to reload, this is normal. Pick 'External tool' from the list of activities and save. Verify you're taken to a page with 'Add a resource' and 'Add an activity' select menus. This is a fallback page expected when modules have several subtypes in the chooser. Now, edit the course again, this time picking 'chat' for the target of the single activity format. Verify you're taken to the edit page for that activity. Now, make sure all your preconfigured tools are set to NOT display in the chooser. Create a new course Edit settings, setting single activity format. Now, select external tool and save Verify you are taken to the edit page for the external tool.
