[logback-user] parameterized logging

[Christopher Piggott]

Oh, you know what ... to the appenders that I did NOT write myself it works:

    log.debug("Hi {}", "chris");
-> 08 Mar 2011 16:56:36.468 DEBUG - com.something.LogResource Hi chris

so the problem is that my home brew Appender (extends AppenderBase) stinks.
