默认的超时时间测试感觉一直变，貌似不能修改连接超时

[hahaha9900]

HttpConfig httpconfig = new HttpConfig();
httpconfig.cacheTime = 0;
httpconfig.TIMEOUT=1000;
KJHttp kjh = new KJHttp(httpconfig);
HttpParams params = new HttpParams();
params.putJsonParams(MerchanDetailEditMerchantPictureJson.Create(shop_id, merchantId, base64Data));
httpconfig.TIMEOUT这个参数应该设置的超时连接吧。要是是的话。它的单位是s还是ms。
