Wildcard to process all namespaces to None or ''

[ToddG]

I'd like to all namepaces, present or not, to be blanked.

e.g.

xmlns:ns1
xmlns:ns2

<ns1:bar> -> bar
<ns2:foo> -> foo
<foo> -> foo

But I don't know all the xml namespaces that might crop up in these docs, so I just want them all to be blanked.

namespaces = { ... "*" : None, # skip all namespaces ... }

Alternatively, it'd be great to just have all the namespace stuff stripped out. Set process_namespaces=False, and then add a flag to strip_namespace=True so that...

<ns1:bar> -> bar
<ns2:foo> -> foo
