JS-242 Allow for alternate logging implementations
Modified code to directly call slf4j.
Updated ivy to bind Java Logging and re-direct apache-commons-logging to slf4j.
Updated POM to use slf4j. Also updated dependencies to the most current version.
Someone still needs to update the POM to redirect apache-commons-logging (JCL) to slf4j and for JCL to not be dragged in as a transitive dependency.
