To be more precise : JSON itself does not assume anything about number 
precision. JavaScript, as well as QJsonValue, do assume that any number 
is a double precision, but nothing in RFC 4627 says that.

libjson (at least) assumes that number values in JSON can be signed 
int64. This specific issue may be better handled in QJsonValue than in a 
QConfig class.
