TC 3.3 Default conatiner

[Keith Wannamaker]

Somethings not quite right in SimpleMapper with
respect to default containers.  If I set up a
default conainer, the note on the global container
is set OK.  But the way it works now is that
PrefixMapper returns a null container for a
URL that is not mapped, which ends the request.

What I can't decide on is the fix -- should
PrefixMapper be returning the default container
if nothing matches, or should SimpleMapper try
the default container if PrefixMapper returns null?
