Suppress logback initialisation messages

Recently I noticed logback logging lots of joran messages, I'm sure it just started happening one day.

With a little playing around I believe that the messages are a symptom of the element deprecation. If you replace the layouts with the correct tags the messages go away.

I used to see this

00:52:57,820 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Could NOT find resource [logback.groovy]
00:52:57,820 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Could NOT find resource [logback-test.xml]
00:52:57,821 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Found resource [logback.xml] at [file:/home/michael/src/stickycode/trunk/net.stickycode.examples/sticky-example-mockwire/target/classes/logback.xml]
00:52:57,954 |-INFO in ch.qos.logback.classic.joran.action.ConfigurationAction - debug attribute not set
00:52:57,962 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - About to instantiate appender of type [ch.qos.logback.core.ConsoleAppender]
00:52:57,971 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - Naming appender as [CONSOLE]
00:52:58,016 |-INFO in ch.qos.logback.core.joran.action.NestedComplexPropertyIA - Pushing component ...
...

But by changing

 <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
    <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
      <level>info</level>
    </filter>
    <layout class="ch.qos.logback.classic.PatternLayout">
      <Pattern>%d{yyyy-MM-dd} %d{HH:mm:ss} %.-1level %thread %logger{36}: %m%n</Pattern>
    </layout>
  </appender>

to

 <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
    <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
      <level>info</level>
    </filter>
    <encoder>
      <pattern>%d{yyyy-MM-dd} %d{HH:mm:ss} %.-1level %thread %logger{36}: %m%n</pattern>
    </encoder>
  </appender>

All the joran/logback messages have disappeared. Yay.
