* mail-display.c, mail-format.c: Redo large chunks of this. The mail display now consists of a vbox in a scrolled window, in which we put multiple GtkHTML objects. This means broken HTML in one part can't corrupt other parts. The headers now scroll with the body. Unrecognized attachments look prettier, but still don't do anything, and will probably be changed later. We can also now display nested message/rfc822 parts and multipart/alternatives with multipart subparts. Oh, and text/{richtext,enriched}, since we had all these ancient sample messages that use it and the lack of support annoyed me. :) Bonobo embeddables are broken right now, but I don't think that's my fault. svn path=/trunk/; revision=2601
