RE: Queue Order Changing

Been working on this since yesterday. I think "add" and "delete" should
probably be part of status, since hash would already be telling me what
hash would be added or deleted. Having them as separate variables would
just confuse things.

>1. account=<string>
>2. hash=<string>
>3. after=<string> - hash that the above hash is now after, or not set
if moved to the top of the queue
>4. status=<lock|unlock|add|delete|move>

If 3 is optional for status:add and status:move. 3 won't be included
for status:lock, status:unlock, or status:delete.

If I remember right, the top 50 will be shown to the user and those are
the ones that they can play with. So, if they found something they
wanted to download, it would get added to the top of the queue. If they
then wanted to move it down to queue position 25, that's their own
doing. But, it wouldn't have any priority other than the queue
