Move IJStatusEchoer and ImporterProcess to logback
Remove checkLibrary call for log4j
Add logback jars
Create LogbackTools from DebugTools

Rather than attempt to do all of the logback configuration
in the ReflectedUniverse, this commits moves the LB logic
out into LogbackTools and only references those static methods
from the ReflectedUniverse. The next step will be to do this
behind a SPI interface.
Minor change to scans-dep comment on Location
Remove explicit logback from lib.dir

logback is also found in the artifacts directory
during execution causing a warning to be printed
during testing.
Migrate test-suite to use logback (or nothing)
Add small whats-new place holder
Temporarily turn configuration debugging on
Fix the scope of logback dependencies in Maven

The Maven build should now pass.
