Fix antispam_cb case sensitive comparison

Since channel names are case insensitive and can vary from session to
session, it's best to homogenize them for comparison purposes.
Remove redundant unicode prefix

Newer python versions use unicode by default, so prefixing strings is
usually unnecesary.
Add parenthesis to print calls for py3k compatibility
Document script hierarchy

A documentation file containing a "map" of the script content and
description of all files (incomplete).
Added several notes
Fully translate to english the whois module

Translated all names, comments, docstrings, references to other modules
and functions... everything. Almost a rewrite, but it's just the same
thing with new names/texts.
Add RAW337 management to whois module

ChatHispano returns this as part of whois responses while using SSL
Add all allready translated modules to the script initialization
Load modules in a relative path way to avoid naming collisions

This is also preferred for Py3K, so let's do it right from now.
