Extend EAttachmentView by subclassing EAttachmentHandler.

So far it only supports extending the attachment pop-up menu, but I
also plan to support extending drag and drop types.  Might even end
up replacing EMFormatHook.

Two subclasses created so far:

   EAttachmentHandlerImage	handles images (built-in)
   EAttachmentHandlerMail	handles emails (defined in mail module)
