Provide a way to remove an event from every participant's calendar.

[fujimotos]

Steps to reproduce

0. Open the calendar app on ownCloud.
1. Create a new event.
2. Add some attendees to the event using the sidebar.
3. Try to remove the event.

Expected behaviour

ownCloud should provide a way to remove a particular event from every
participant's calendar.

Actual behaviour

We need to click each participant's event and remove them one by one.

Server configuration

ownCloud version: (see your admin page)

ownCloud 10.0.10 (stable)

Additional Info

My company uses ownCloud Calendar for setting up corporate meetings.
Since we have all-hands mettings occationaly, the number of participants
can be very large.

Right now it's huge pain to remove such events (e.g. cancelled meetings)
from calendars, because we need to click and remove it manually from
EVERY atendee's calendar.

Google Calendar allows the event organizer (i.e. someone created a event)
to remove a particular event completely. Owncloud should provide some way
to do so.

This is Part of caldav scheduling. This should work. Needs debugging ...

@fujimotos How did you add your attendees - by mail or by the username?

[fujimotos]

By username. I usually type attendee's user name (like "fujimoto") into
the input box, and click on the suggested name.
