Updated Maven's pom.xml to match the content of the jardesc file (in build/build-bin-jar.jardesc).

1. Rename the target jar to  "Mambu-APIs-Java-3.3-bin.jar" and place it in the build directory
2. Add to this jar configuration files (config.properties and logger.properties) as well as the README.md and pom.xml
3. Exclude demo files from the jar

4. Remove configuration for building 'jar-with-depenedcies' jar.
