Subject: [PATCH] fuse/blackmatch: update json handling to support simplejson
 v2

simplejson v2 returns strings as either unicode or str, depending upon its
mood.  thus the interpretation of the node's json repr of a directory, and
the serialisation of strings in the json based rpc both exploded when built
against simplejson v2.  this makes both of these places liberal in their
acceptance of either str or unicode.
