upgrading to jxt 1.6. broke jingle-interop-demos

[fippo]

rebuilding stanza.io with jxt upgraded to 1.6 (from 1.4) results in the following error when trying a jingle-interop-demo call:
Uncaught TypeError: Cannot assign to read only property 'transType' of [object Object]
in
exports.extension = function (ChildJXT)'s set function at
child[prop] = value[prop];

Should be fixed in 1.6.1
