Renamespace Devalloc and Que

Move them under the Biz root so that we know they are specific to Biz stuff. Biz
is for proprietary stuff that we own.

I also had to refactor the bild namespace parsing code because it couldn't
handle a namespace with 3 parts. I really need to get that namespace library
written and tested.

+## Ques
+
+A que is a multi-consumer, multi-producer channel available anywhere you
+have a network connection. If you are familiar with Go channels, they
+are pretty much the same thing. Put some values in one end, and take
+them out the other end at a different time, or in a different process.
+
+Ques are created dynamically for every HTTP request you make. Here we
+use the `que` client to create a new que at the path `pub/new-que`:
+
+    que pub/new-que
+
+The `que` client is useful, but you can use anything to make the HTTP
+request, for example here's the same thing with curl:
+
+    curl https://que.run/pub/new-que
+
+These requests will block until a value is placed on the other
+end. Let's do that now. In a separate terminal:
+
+    echo "hello world" | que pub/new-que -
+
+This tells the `que` client to read the value from `stdin` and then send
+it to `example/new-que`. Or with curl:
+
+    curl https://que.run/pub/new-que -d "hello world"
+
+This will succeed immediately and send the string "`hello world`" over
+the channel, which will be received and printed by the listener in the
+other terminal.
+
+You can have as many producers and consumers attached to a channel as
+you want.
+
+## Namespaces
+
+Ques are organized into namespaces, identified by the first fragment of
+the path. In the above commands we used `pub` as the namespace, which is
+a special publically-writable namespace. The other special namespace is
+`_` which is reserved for internal use only. You can't write to the `_`
+namespace.
+
+To use other namespaces and add authentication/access controls, you can
+[sign up for the Power package](/_/index).
+
+## Events
+
+Just reading and writing data isn't very exciting, so let's throw in
+some events. We can very quickly put together a job processor.
+
+    que pub/new-que --then "./worker.sh '{msg}'"
