Go JSON reads/writes incorrect data for list<>

Example to reproduce: Given a list<string> holding one "element", the following JSON data are rendered:

"lst":[11,1,"element"]

The expected sequence would be:

"lst":["str",1,"element"]

This is due to the method OutputElemListBegin(), which JSON inherits from SimpleJSON. This method writes the field type as a byte value, without passing it through TypeIdToString(), which is incorrect for JSON.

EDIT: Similar problem appears when a "lst" should be read.
