Allows processing of wsdl that has elements with an undefined namespace

Signed-off-by: Pamela McA'Nulty <pamela@webreply.com>

-- If one tries to grab a schema item using the helper methods, if that item doesn't exist and the namespace is not in the BUILT_IN_NAMESPACES list then throw a SchemaError.  Now failure to specify an import dependency will result in an error like:

     ZSI.wstools.XMLSchema.SchemaError: schema "urn:webservices" does not import namespace "urn:base"

when "item.getTypeDefinition()" is called and the "type" attribute value QName is in a namespace that hasn't been declared as a dependency

So basically this throws errors when can't find a schema item that is supposed to be defined, rather than just returning None most of the time,  which is always an error condition.

        Utility.py -- added a CollectionNS class that keys items via
            (targetNamespace, name).

        WSDLTools.py --

            Made WSDL Collections into CollectionNS instances,
            this fixes problem with collisions, caused by wsdl:imports,
            between items with same name but defined in different
            targetNamespaces.  So now all items can be accessed via
            (namespace,name), but ONLY those items defined in
            WSDL.targetNamepsace (not an import.targetNamespace) can
            be accessed using just 'name'.

            Also changed how portType is "loaded".  Now instead of
            dropping all the operation nodes in "load", I drop
            the portType node into "load".  This makes sense because
            portType really should know about itself, and the
            XML Schema definition of "portType" includes an "anyAttribute"
            and I need to make this stuff available.  I may change the
            other WSDL information items to do this to be consistent.

 	Utility.py -- fixed bug in _clone_node patch.  This method
          was being called with qualifiedName for namespaced attributes,
          and bombing.   It is supposed to be called like so:

     getAttributeNodeNS(self, namespaceURI, localName)

          Really could remove the if/else clause here but I
          decided to leave it there just to keep the 3 distinctions
          in the code.

I fixed that fact that Notation and Entity were not be found. I changed them
to use the qualified name like the rest of the symbols from xml.dom.minidom.

I also discovered that a RecursionError was being thrown, but RecursionError
didn't exist. I created simple sub-class of Exception to rectify this.
