Created attachment 328330
Allows drag&drop of attachments from message view to desktop

Hej,

this patch allows drag&drop of attachments to the desktop by saving the requested attachment to a temporary file and passing the URL of that file in the drag object. The patch has still two issues: 1) '/tmp' is hard coded... It seems nsIFileUtilities::getTempDirPath() could help here, but how do I instantiate such a component?
2) The name of the temporary file is the same as stored in the attachment, however as it's a temporary file, it should have a unique name (like returned by mktemp(3) under Unix). nsIFileUtilities::newTempFileName() looks promising, but could it be that there is no implementation for that method?
