In support.js, the functions http_get_json, ajax_http_get_json and ajax_http_post_json now calls the supplied error callback if the server returns invalid JSON (e.g. because of a crash). The function gftranslate.translate in gftranslate.js returns a JSON value containing an error message (since it doesn't have an error callback). This should result in fewer situations where "nothing happens" and the user doesn't know if it is beacuse the server is slow, or if there was an error.
