Removed largely unused catalina.base system variable, created test-resource persistence.xml's to allow for use also with EclipseLink (slight risk of persistence.xml falling out of sync with one in src/main/resources though), upgrading EclipseLink to 2.5 which is now on Maven Central, moving output logs to easier-to-see target instead of target/test-classes folder
