From 67ce5f3b140525c2f5944270a9383616f9d67923 Mon Sep 17 00:00:00 2001

Subject: Add DnD support to e-selection.c.

Avoid listing calendar and directory targets explicitly, so that
e-selection.c contains the one and only master list.  Still need
to figure out how to centralize "text/x-source-vcard".
