[JDEV] misc protocol discussion

In message packets we have the type="" attribute available for
special built-in message types, most obviously for errors.  And in a
status packet we have the same attribute but it's on the <say></say> tag
instead.  Would anyone be against moving it up to the status tag to be
consistent with message, and it feels more appropriate there anyway:
  <status type="online">
	<say>Groovin</say>
	<priority>10</priority>
  </status>

If everyone is in agreement, I can do this before 0.6.
