Comment 1 for bug 148015

Implemented the
* avatar field in the business card window
using dnd. You just drag the image to the desktop and you get it as an image file. Since this is using tkdnd it wont work on Mac.

Adding a similar mechanism for the avatar roster is currently not possible since this will interfere with the contacts being a xmpp uri drag source. If this is going to be possible there must be a different selection mechanism for the actual contact and its avatar. A bit messy, at least for the moment.
