Use of System ClassLoader didn't find custom logging enhancer

[dclements]

When using the logback appender I tried adding my own LoggingEnhancer, but it failed to load with a ClassNotFound exception (which was swallowed).

Investigation revealed that the problem was that the logback appender was loading it using the system classloader. Switching this to the thread context classloader (with ch.qos.logback.core.util.Loader#loadClass) worked fine.
