Added node types

Now inside each netnode (and, hence, inside each node) there is
a field showing the type of the node. This is required because,
at least in response to requests by the filter, proxy nodes and
shadow nodes will have different jobs to do and the server-side
implementation of filesystem RPCs in nsmux would need to know
what actions they are expected to carry out.
