New Web Service mod_lti_get_ltis_by_courses

Note: Version numbers are bumped because a new web service is added into the Mobile app service and also in the module.

1. Create a course with a teacher and a student.
2. Create a couple of external tool activities. Hide one of the activities.
3. Enable "Mobile services": Plugins ► Web Services ► Mobile
4. Create a Token for the teacher and the student:
   • Click on Site administration ► Plugins ► Web services ► Manage tokens
5. Next, you can do a couple of CURL REST call simulating a WS client with the teacher and the student user
   • You need to replace the wstoken and the URL of your moodle instance:

     curl 'http://localhost/m/stable_master/webservice/rest/server.php?moodlewsrestformat=json' --data 'wsfunction=mod_lti_get_ltis_by_courses&wstoken=ffbe3a3002f235bf9d01fd9369e10b66' --compressed | python -m "json.tool"

6. Confirm that
   • As student you only see the visible external tool activity, and you see all the external tool configuration settings except the one reserved for managers (you should see only: id, coursemodule, course, name, intro, introformat, launchcontainer, showtitlelaunch, showdescriptionlaunch, icon, secureicon)
   • As a teacher you see all the external tool activities and all the settings
7. You can also specify which courses to retrieve, (replace courseids..5 with a valid number in this request)

   curl 'http://localhost/m/stable_master/webservice/rest/server.php?moodlewsrestformat=json' --data 'courseids%5B0%5D=5&wsfunction=mod_lti_get_ltis_by_courses&wstoken=ffbe3a3002f235bf9d01fd9369e10b66' --compressed | python -m "json.tool"

8. If you use a course id where you are not enrolled, you will receive a warning "No access rights in course context"
