Update copyright/license/author/contributors information

Make sure all files have encoding set to utf-8 unless they already have an encoding
Added COPYING with contense of GPL-2
Added plugin name prefix to all log output. This should take the form of self.log.severity("Plugin: message"),
when not logging from plugin.py use: "Plugin/file_without_dot_py: message"
Bantracker: Made the confgure() function do something, it also creates an initial database if it doesn't exist
Encyclopedia: Made the configure() function do something, it also creates an initial database if it doesn't exist
PackageInfo: Improve the configure() function, it also now creates some initial .list files and prompts to run update_apt and update_apt_file
This goes some way to getting an "ubottu" package together, all we need to do is patch supybot-wizard to download the plugins
from bzr and put them somewhere supybot will see them, then the wizard will do all the initial setup
