itip-view: Offer to show other parts from multipart/alternative
I received a message that was in multipart/alternative format and contained three alternative versions of the content: text/plain, text/html and text/calendar. Evolution automatically chose text/calendar version and displayed only the calendar invitation part. The issue is, in text/plain and text/html parts there was much more content than in text/calendar part and I was unable to see those parts. I want to suggest to add a menu option or button to Evolution to display other alternative parts in case of a multipart/alternative message.
