Feature: Add internal Bans Storage

[Torndeco]

• Read & pickle bans into a file..

** Info containing guid / ip / date & time / player name / server / logfile

** Will allow to reference to check if a player guid / ip is already banned, avoid multiple entries in bans.txt

** Also will be needed for rpt / console banning options in #22

• Add external python script so admins can lookup player bans. So admins can lookup when / which server / log file(s) resulted in player ban.
