Title: 把 proposed 和 backports 的源都去掉了

"Pre-released Updates (oneiric-proposed)". The testing area for updates. This repository is recommended only to those interested in helping to test updates and provide feedback.

"Unsupported Updates (oneiric-backports)". As the name states, these are unsupported versions of future packages which are still in development. Packages may contain new features, may introduce new interfaces, and have not been sufficiently tested to be included in the 'proposed' repository.

这两个源都是不推荐的。
去掉 proposed 后，我们就不会那么频繁地需要跟进 Ubuntu 的软件包了（比如这次的 casper）。
