The iCalendar RFC allows comments in an event reply to e.g. indicate a reason for declining. This patch implements sending an additional comment if the usual functions `gnus-icalendar-reply-[accept,decline,tentative]` (bound to `i a`, `i d`, `i t`) are called with a prefix argument.

Please let me know any feedback regarding the patch and commit message formatting.

Notably this only implements the comment functionality for the functions mentioned above and does not include the buttons defined in `gnus-icalendar-event:inline-reply-buttons`, as I am not sure how the `read-string` for the user's comment should be implemented for them.

Best,
