[patch] support version for EAR modules

Currently the m2eclipse plugin with MNGECLIPSE-688 support EAR and EJB projects. If you close one project, the jar from local repository is used and deployed on server but with name like artifactId-versionId.jar.

To explain use the mavenized-jboss-seam-booking.zip attached to MNGECLIPSE-688 :

• launch eclipse
• Import the projects
• Edit jboss-seam-booking-parent/pom.xml to add the following
  <repositories>
  <repository>
  <id>jboss</id>
  <name>Jboss Repository</name>
  <url>http://repository.jboss.com/maven2/</url>
  </repository>
  </repositories>

• left click on jboss-seam-booking-ear
• In Java EE > Generate Deployment Descriptor Stub : it will create jboss-seam-booking-ear\src\application\META-INF\application.xml
• add the following to application.xml
  <module>
  <ejb>jboss-seam-2.0.2.SP1.jar</ejb>
  </module>
• create a new JBoss server. Use JBoss, a division of Red Hat > JBoss 4.2 AS server
• choose your settings accordingly, then add jboss-seam-booking-ear to the server
• back in eclipse project explorer, left click on datasources\jboss-seam-booking-ds.xml > deploy to server
• start your server. On one occasion, jboss-seam-2.0.2.SP1.jar was not deployed correctly.
  After stopping the server, cleaning up $ {JBOSS_HOME}\server\default\tmp and ${JBOSS_HOME}

  \server\default\work and restarting eclipse, it deployed correctly.

• In your browser, go to http://localhost:8080/seam-booking/
• Ok it works !

• left click on jboss-seam-booking-ejb
• In Run As > Maven Install
• close the jboss-seam-booking-ejb project
• select server and clean it
• start server => the server start with error.
• jboss-seam-booking-ejb.jar is defined in application.xml, but jboss-seam-booking-ejb-0.0.1-SNAPSHOT.jar is deployed.

• Apply the attached patch.
• left click on jboss-seam-booking-ear
• In Run As > Maven generate-resources
• copy target\jboss-seam-booking-ear\META-INF\application.xml to src\main\application\\META-INF\application.xml
• start server
• In your browser, go to http://localhost:8080/seam-booking/
• Ok it works !

In summary, you can open or close era module projects.
