Deactivate Create Appointments action

This feature request is a part of the Calendar Revision III.

1 Initial Problem

It is difficult to distinguish session dates from other dates in a course or group calendar. If you are working with sessions and someone does not know the session tool, the action "Create Appointment" can cause "wrong" appointments to be created.

Possible scenario: If the calendar serves as a timetable, which is filled with session dates due to automatically created sessions, it should not be possible to add other types of dates to the course or group calendars. The button "Create Appointment" is displayed very prominently in the calendar, but does not make sense in the scenario described and may lead to confusion that lecturers want to create new appointments, but these are not correctly displayed to course members (e.g. due to permissions).

2 Conceptual Summary

In the global settings of the calendar it should be possible to set whether the creation of own dates in course and groups is allowed or not.
This would allow different scenarios:

1. Allow setting own appointments for all calendar types
2. Set own appointments only for personally created calendars 
3. Do not set own appointments
