- Removed hostname lookup (it blocks, and you can always do it yourself)
- Reorganized debug levels (after hints from Axel M�ller):
0 Startup message and errors
1 Connection logging
2 Meta protocol information
3 Verbose meta protocol (includes copy of transmitted requests)
4 Packet information (logs transmission/errors of UDP packets)
5 Verbose packet information (every single byte, not implemented yet
to protect ourselves from filling up /var/log directories)
- Made log messages more consistent
