[kronolith] how to import *.ics calendar entries from a multipart mime email received with IMP into KRONOLITH

[Christoph Haas]

Hello,

I am looking for a conveniant way for importing calendar-entries  
(*.ics-files), that are part of a multipart-mime-email, out of IMP  
into KRONOLITH. Since Google was not my friend, I have to ask here ...

When I click on the calendar-attachment, is just a window with the  
plaintext VCALENDAR-entry shown, instead of import to KRONOLITH.

This is for example common with ticket-booking-emails from "Deutsche  
Bahn", or other traveling services, airlines etc.
They attach a *.pdf-file with the ticket, an *.ics-file with the  
traveling plan, a plaintext and a html text:

Subject: =?UTF-8?Q?Buchungsbest=C3=A4tigung_(Auftrag_ABC123)?=
MIME-Version: 1.0
Content-Type: multipart/mixed;
	boundary="----=_Part_1266891_1638770165.1456756571410"

------=_Part_1266891_1638770165.1456756571410
Content-Type: application/octet-stream; name=ABC123.pdf
Content-Transfer-Encoding: base64
Content-Disposition: attachment; filename=ABCD123.pdf

[...]

Sure I can save the *.ics-file to my harddisc and afterwards import  
this file. But this is not really conveniant.

Is there a way to import the calendar-entry _directly_?

Thanks!
Christoph.
