core, setup: huge cleaning: - moved directories from src and frontends/src to sat and sat_frontends, which is the recommanded naming convention - move twisted directory to root - removed all hacks from setup.py, and added missing dependencies, it is now clean - use https URL for website in setup.py - removed "Environment :: X11 Applications :: GTK", as wix is deprecated and removed - renamed sat.sh to sat and fixed its installation - added python_requires to specify Python version needed - replaced glib2reactor which use deprecated code by gtk3reactor sat can now be installed directly from virtualenv without using --system-site-packages anymore \o/
