Added option parsing.
This commit allows users to customize their IRC user name, nick name,
and server. The user name, if not specified, is taken from the
environment variable USER. The nick name, if not specified, is taken
from IRCNICK. The nick name cannot exceed 63 chars (which is way more
than what is currently accepted by most IRC servers).
