Add actions

~~Second commit added~~

Fixes #258.

I got bored and this changed from changing debian versions to adding actions. https://debian.org/stable/allpackages (<-- literally all packages, lotsa text)

The actions look like they do in my [IRC client](http://quassel-irc.org/).
This is not going to work.
OpenCV 2.3 is ancient, its last version was released on 2011-09-12, most distributions have OpenCV 2.4 instead. If we depend on 2.3, a system with 2.4 will not be able to run qTox.

Besides, the debian release is getting close, soon 2.4 will be in stable.

Can you resend the PR without changing the packages dependencies ?
