Cleanup svg export namespace handling

All smil animations are inside the http://www.w3.org/2000/svg NS
for svg - ODF places e.g. animateMotion into smil, their path attr
though into svg. Flattened namespace now into only default (svg) and
the ooo prefix. Killed all superfluous NS decls, creating SvXMLExport
with EXPORT_META only adds XML_NP_XLINK, XML_NP_DC, XML_NP_META, and
XML_NP_GRDDL to the known-namespaces map.
