Remove unsused FilteredPatternLayout (#1271)When upgrading to logback 1.2.0, this class gets broken. No logback-*.xmlfile (that I was able to find) is referencing it.(cherry picked from commit e40621441b4b6958e6030854a8f348095cef84f2)
Fix and unify logback*.xml configs (#772)* using the %line _may_ lower performance, but I was not able to observe any difference when running the drools build (mvn clean install -T10). I believe the line number gives useful info when trying to determine what is going wrong (especially on Jenkins).
