so far, requestInfo failure where logged as a warning, and an empty disco was returned.
This prevented the requesting entity to know about the error, so now the error is logged and re-raised.
CancelError are converted to TimeoutError (requestInfo is only cancelled on timeout).
An empty disco is still cached in case of failure, to avoid re-waiting for the entity on next request.
- 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/
