[aur-dev] [PATCH 3/3] JSON-RPC: convert null and "" in info queries.

[Christopher Brannon]

When processing a query of type=info, the code in aurjson.class.php
was not gracefully coping with attributes which have a value of null
or the empty string.
For example, if the URL field of an object was "",
the JSON-encoded result would contain:
{"URLPath":"[PKGBUILD error: non-UTF8 character]"}
This patch insures that NULL and "" are handled properly.
