  Added:       logging/src/java/org/apache/commons/logging/impl
                        AvalonLogger.java
  Log:
  Added AvalonLogger which wraps the logger used by the Avalon framework. Also added an optional dependency on avalon-framework.jar. Added better warnings to build about which loggers are going to be created. Submitted by Neeme Praks.
