Code review comment for lp:~bilalakhtar/aptdaemon/unity-integration

Well, the only purpose why I embedded this thing inside aptdaemon was because it was more closely tied to the progress bar. That isn't an efficient way to do this, and hence I guess it might be better to just leave things in aptdaemon as it is. I don't think any other app using aptdaemon would need launcher integration (except software-center, where it'll be implemented very differently).
