Currently we only show writable calendars in the calendar row, but
for read-only events, the read-only calendar must be selected. But
that's impossible because it's not in the model.
Change the model to a flattened list as follows:
+ FlattenListModel -----------+
| |
| + writable calendars -----+ |
| | | |
| | - Calendar 1 | |
| | - Calendar 2 | |
| | - Calendar 3 | |
| | [...] | |
| | | |
| +-------------------------+ |
| + read-only calendars ----+ |
| | | |
| | - Calendar 1 | |
| | [...] | |
| | | |
| +-------------------------+ |
+-----------------------------+
The read-only calendars list only ever has 1 item: the calendar
of the current event, and only if the event is in a read-only
calendar.
