Add users as project administrators to each newly created project

This is a fully fledge example, of how to use the Listener API, to add users as project administrators to each newly created project.

Since this Listener needs extra configuration, it cannot be automatically deployed by adding a @Component annotation!

Instead you must add an appropriate <bean> configuration to ~/CB-../tomcat/webapps/cb/WEB-INF/classes/my-ApplicationContext.xml, e.g.

   <bean id="assignAdminAccountToNewProjectListener" class="com.intland.codebeamer.event.impl.sample.AssignAdminAccountToNewProjectListener">
      <property name="accountId" value="1;44"/>
   </bean>
