Improving Attendance Agenda + New Display Mode

We have merged the Attendance and Attendance-Overview agendas. In the Attendance agenda you will now find the switch between display modes:
a) the entire month of one person
b) one day more people (formerly agenda Attendance-Overview)
c) monthly sums of more people (new one!)
With the new display mode, you can easily see the monthly attendance results of multiple users at once, and even edit them in the table.
