+Subject: luci-lib-json: ignore null keys to allow encoding empty objects
+
+There is currently no way to encode an empty object {}, as empty tables are
+encoded as empty lists [].
+
+With this patch, encode() will ignore table fields with the key json.null (which
+doesn't make sense anyways). This allows adding a field with key json.null to
+force encoding it as an object.
