Major underlying changes to namespace handling. Each namespace is handled by its own class which extends Namespace_Default. Much greater customization/pluggability potential, at the possible expense of some code reusing (though code reusing has been avoided thus far). Also a bit better handling of page passwords [SECURITY].
