- marking release 0.9.4
- a small improvement to ConverterTest

- Added LogbackException (extending RuntimeException) 
- Added a throws "LogbackException" to Appender.doAppend method 

These changes allow "transactional" logback modules, e.g. logback-audit to 
throw exceptions. Other best-effort modules may catch LogbackExceptios effectively
hiding them from the user.

The autoConfig method in ContextInitializer class now throws a JoranException 

Fixing bug 70 involving the %throwable conversion word.

Fix for bug report 63.

Users can make call to log4j using log4j's TRACE level. TRACE is part 
of org.apache.log4j.Level and not o.a.l.Priority as it was introduced in
log4j 1.2.12.
