Update README.md to reflect conf-example.py file name change
Big refactoring in order to use argparse and ConfigParser module instead of using python import. Add possibilities to use custom config files
Ignore local .conf files
Fix maxitems command line option never parsed
Add various options to support streaming app.net feed or other microblogging feeds
Backward compatibility on N parameters. No more required to first cd to the feed2twister folder.
Update readme
Merge #6 by @milouse (config file + argparse)

NOTE: If you upgrade, you need to create feed2twister.conf
(copy feed2twister.conf.example) and edit it so that it contains
similar settings to those you had at conf.py
