[logback-user] Logback configuration

Hello Andy and Anders,

We've modified Joran to add this feature yesterday.

The repository version now allows you to set an <include> element in a configuration 
file, and set a file="" attribute. This attribute can be specified by using a property.

We could have:

   <include path="${path.to.file}" />

The target file must use the following elements:

  <!-- add here any configuration element: Appender, layout, logger, ... -->

Would that do the trick you, Anders?

Making this part of Joran (possibly providing a short sample that gets everything from a property) seems like a great solution that could be helpful in many situations (especially with conditionals and regex captures).
