remove unnecessary new lines in legion logs

they only look nice with base console logging, it causes little mess after adding --logdate or sending logs to syslog

Example:
```
Thu Apr 11 14:13:30 2013 - 
[uwsgi-legion] --- WE HAVE QUORUM FOR LEGION legion1 !!! (valor: 101 uuid: f7b10472-f221-45ad-9298-5f7ca8298d22 checksum: 4882 votes: 2) ---
```
