[MlMt] Dragging messages as an attachment (r5107)

[Scott A. McIntyre]

Hi,

With the current 5107 build, I can no longer drag a message from my 
message view onto an open compose window and have it attach.

Instead, I get a:

message://%3c51C9423A-61E2-4562-80CC-A7C5E23317CE@gmail.com%3e

Reference...

Is this something I've done, or something MailMate's done?

Scott
