custom namespace/node type import tool

[Brian Moseley]

in working towards an offline tool to import custom namespaces and node 
types, i found that i needed to make some small changes to 
NodeTypeReader and DOMWalker so that i could subclass NodeTypeReader and 
access the namespaces specified in the node type definition file. i 
opened JCR-142 and attached a patch.

you can view the code for the import tool (work in progress) at 
<http://svn.osafoundation.org/server/commons/trunk/jackrabbit/>. i plan 
to wrap a maven plugin around it so that i can use maven to initialize 
my repository while building my server distribution. the importer could 
be used in many other ways, of course, tho i haven't considered in 
detail any use cases but my own :)

if there's interest, i'd be happy to donate the code to the asf (it's 
under the apache license now).
