Minor python3 module structure compliance and tweepy-derived classed won't load on start
Addressing Issue #2:
- Moved listeners into a separate package.
- Each implementation is loaded if its backend is available.
Removing old code (cruft) from the fetching script.
Now it only starts, load simple configuration from command line and does nothing until Ctrl-C is issued, simulating the whole process.
Fixing the language detector call. Was using the old Python 2.x guessLanguage module.
Issue #2: Polishing stream handler and updating main script.
