master 2194284: Enable replying to an ical event even when not an attendee

[Lars Ingebrigtsen]

branch: master
commit 2194284c55ba3f4f9859d2b65d21314446fc6a09
Author: Christophe Troestler <Christophe.Troestler@umons.ac.be>

    Enable replying to an ical event even when not an attendee
    
    * lisp/gnus/gnus-icalendar.el
    (gnus-icalendar-event--build-reply-event-body): Display a warning
    instead of barfing when user is missing from attendee list.
    
    When the user identity is not present in the attendee list, an error
    is triggered making replying to such an event impossible (the reply
    message not being even composed).  This replaces it with a warning.
    This is necessary because one may receive events that the organizer
    did not set up well and it is up to the user to decide whether or not
    to reply to them (bug#41723).
