localName is leaked as a global variable

[NickMackz]

The localName variable is leaked as a global variable in this section of code:

Jsonix.XML.QName.key = function(namespaceURI, localPart) {
	Jsonix.Util.Ensure.ensureString(localPart);
	if (namespaceURI) {
		var colonPosition = localPart.indexOf(':');
		if (colonPosition > 0 && colonPosition < localPart.length) {
			localName = localPart.substring(colonPosition + 1);
		} else {
			localName = localPart;
		}
		return '{' + namespaceURI + '}' + localName;
	} else {
		return localPart;
	}
};
