12 - query engine should not redefine the default namespace

[joshsh]

Currently, the query engine redefines the default namespace (that is, the
namespace of a QNames such as :foo and :bar) when it is created.  By
default, the default namespace is
<http://ripple.fortytwo.net/code/examples#>, which points to an RDF
document containing a few handy Ripple programs to, say, kick off a demo
with.  That's fine when the default namespace has not already been defined,
but irritating when you're returning to an environment in which you _have_
already defined it, presumably with good reason.
