Removed unused commons-cli 1.2 jar

Removed unused commons-cli jar: barcode4j has an optional dependency on it but only if used from the command line (which is not the case in OFBiz); Groovy has a dependency on Commons CLI, antlr, asm but it uses a copy of them bundled in groovy-all jar, so removing the pathelements set for the ant path id "groovy.class.path".
