#16 Object names are not escaped

[Stephen Lynch]

if you have the object described by the following JSON
{ "\"key\" ": "\"value\"" }
Stored in memory jaula will serialise that as
{ ""key"": "\"value\"" }

according to http://www.json.org/ the object name should be treated the same was as a value string.

(inefficient) patch attached.

[Stephen Lynch]

Create a temporary Value_String containing object names
