David Gibson 05898c67c1 dtc: Allow multiple labels on nodes and properties ...

At present, both the grammar and our internal data structures mean
that there can be only one label on a node or property.  This is a
fairly arbitrary constraint, given that any number of value labels can
appear at the same point, and that in C you can have any number of
labels on the same statement.

This is pretty much a non-issue now, but it may become important with
some of the extensions that Grant and I have in mind.  It's not that
hard to change, so this patch does so, allowing an arbitrary number of
labels on any given node or property.  As usual a testcase is added
too.
