files reorganisation and installation rework: - files have been reorganised to follow other SàT projects and usual Python organisation (no more "/src" directory) - VERSION file is now used, as for other SàT projects - replace the overcomplicated setup.py be a more sane one. Pyjamas part is not compiled anymore by setup.py, it must be done separatly - removed check for data_dir if it's empty - installation tested working in virtual env - libervia launching script is now in bin/libervia
