登录成功，下载失败。

What steps will reproduce the problem?
1. 填写登陆账号密码及DeviceID
2. 启用代理（Sock5）
3. 登陆成功，在主页搜索也成功。下载提示失败。

What is the expected output? What do you see instead?
我是通过Tunnelier连接SSH账号，开的本地代理，下载时有如下��
�示信息：
11:08:36.796 (unrecognized proxy protocol) connection from 127.0.0.1:4358 
failed: Unsupported client protocol; the client may be expecting a regular HTTP 
proxy.

What version of the product are you using? On what operating system?
XP 系统，APK Downloader版本1.1.1

Please provide any additional information below.
请问是不是不支持Sock5代理的关系，可以增加Sock5支持吗？
