Set up Slf4j and Log4j2 for logging

Browse Source 
All logs are kept in the "logs" directory as before.
The most recent logs (up to 20MB) are kept in cosmic-log.log in the root of "logs".
Previous logs (either from previous server starts or logfiles that exceeded max size of 20MB) are stored away in directories according to their creation date.
