Convert to maven project.

Move all files into the maven directory tree structure and delete the
ant+Netbeans project.  Create a script to install the IBM DB2Jcc driver
into the local maven repository.

The application is now working by running
  $ mvn package -DskipTests # skip lengthy live DB tests
  $ java -jar target/ReserveWithUsApp-1.0.jar

The application properties are placed automatically into the JAR. Simply
package again after making any code changes to use the up-to-date JAR.
