#23 XmlRpcJsonSerializer outputs invalid JSON strings

[Anonymous]

specifically, strings are bracketed by single quotes instead of double quotes. this isn't correct according to the spec at http://json.org/. I believe the problem is in XmlRpcSerializer.java, and I've uploaded a version of the file that should fix this, though I haven't tried to compile or test it.
