Add travis (again)

Beside making it work again, there are some improvements:

Linux side:

* use minimal supported Qt version, currently it's 5.3
* use minimal supported GCC version, currently 4.8
* use newer ffmpeg version to compile against - 2.8.5
* compile qTox 2 times, first run without support for optional dependencies
* use ubuntu 14.04 for building (less deps needs to be compiled/added from PPAs)

OSX:
* add osx to build targets
