New Revision: 846

Added:
   
logback/trunk/logback-classic/src/main/java/ch/qos/logback/classic/turbo/DebugUsersTurboFilter.java
Modified:
   
logback/trunk/logback-classic/src/main/java/ch/qos/logback/classic/ClassicGlobal.java
   
logback/trunk/logback-classic/src/main/java/ch/qos/logback/classic/joran/action/ConfigurationAction.java
   
logback/trunk/logback-classic/src/main/java/ch/qos/logback/classic/turbo/TurboFilter.java

Log:
ConfigurationAction now pushes and pops the context to and from the 
objectStack, so that it is usable
by following actions.
Added an implementation of TurboFilter that allows debug level for selected 
users only.
Work in progress: the <user> element still makes Joran caugh a bit.
