Code review comment for lp://staging/~ricardokirkner/lalita/trunk-easy_install

Adapt the code so that it is easily "easy_install"-able. Just moved some stuff around, added the necessary packaging stuff and slightly changed the ircbot.py file to use a configuration file passed by parameter.

From the code on this branch I already added lalita to the PyPI, and it worked alright (I could 'easy_install lalita').
