Inproved SyslogAppender

I found today an issue reported that looks like the one i am facing : the
difficulty to handle tag for syslog message routing with Log4j Syslog Appender.
On this issue, it was advised to use ConversionPattern Layout to handle the tag
prefixing the real message payload. 

I.E, this workaround only work for small log message as the SyslogAppender
slice long message in < 1024 chunks. In order to prevent the tag to only appear
on the 1st syslog message, i've diverted the facilityprinting options that
limit the usage of tags to the facility names. To let the user define its own
tag, i've added a TagLabel property to the appender, renamed FacilityPrinting
to TagPrinting and not to be too code intrusive, i've had a little hack to
suffix the SyslogAppender header string with it.

I hope it will help someone out there.

Regards,

Mathieu
