Initialize logback is it is present in CLI

Browse Source 
This (empirically) fixes gh-726 using a new utility
(LogbackInitializer) in the loader tools. If anyone has enough
Gradle fu to understand where to put it (after the classpath is established
but before compilation) we could do the same thing in the Gradle plugin
(and that would fix gh-724).
