Subject: [PATCH] Set client timeout limit in chainGetJSON() (#2482)

By setting a client side timeout one can avoid net::ERR_NETWORK_IO_SUSPENDED errors caused by the OS network layer being suspended [1]. This allows the client to handle higher level errors.

The jQuery.getJSON() function does not have a parameter for timeouts.
