Subject: [PATCH] Add a nice error message when json failes to parse and fix
 Makefile rule

I had a json that wouldn't parse (trailing comma) but it was an
odd php error about iterating over a null.  So this should give a
slightly better error.

Also, .inc files are no longer used.  Remove the Makefile references.
