Architecture upgrade:

   * Attachment support, e.g. pic, link, etc.

   The update() of Renren and SinaWeibo support image upload.

   * Asynchronous I/O.

   See the snscli-async for how to use it.

New platforms:

   * RenrenFeed.

   A merge of several RenrenXXX platforms.

The long request of read/ write pictures are prototyped. In the return object of home_timeline, you will find the 'attachments' structure. To upload pictures, use the 'pic=xxx' parameters. Picture upload are currently supported on Renren and SinaWeibo. 

Asynchronous facilities can make the development of applications easier.
