Feature Travis

https://travis-ci.org/massix/server-game/builds/19871850 \o/

Now we have the ~~Software Factory~~ Travis Continuous Integration going and building fine!

We might want to switch the test phase into the script one, I'm not sure on where that should go..

@dchilot: could you please also integrate the gcov tests (I will try to do something for valgrind if needed)

This PR also includes a very small bug fix for Linux systems (we had issues in test_hello.cpp, I don't know if it is because of the submodule or not.. we will have to check), commit 395db01

Once this PR will be integrated, I will activate the hook for the integration repository (and disable the one on my side), then we will all be able to modify the settings.


We can also add some notifications
