Log:
- Logback-classic default configration process will now
automatically print status data on the console in case of warnings
as well as errors. Previously, status data was printed only in
case of errors.
- In case multiple configuration files are found on the class
path, ContextInitializer will now emit a warning. This fixes
LBCLASSIC-85.
