Hi everyone,

I've fixed two very simple but long-standing SyslogAppender bugs, 
LOGBACK-401 ("SyslogAppender prints %PARSER_ERROR[nopexXXX] when 
suffixPattern doesn't start with [") and LOGBACK-141 ("Syslog messages 
over 64K are discarded"): 

https://github.com/qos-ch/logback/pull/60
http://jira.qos.ch/browse/LOGBACK-401

https://github.com/qos-ch/logback/pull/59
http://jira.qos.ch/browse/LOGBACK-141

I hope these fixes could be included in the next version of Logback.
This is my first contribution to Logback, so I don't know if a 
GitHub pull request is the proper procedure (if it's not,
please let me know).

Best regards,
Pasi
