1) 'ant jar' in modules/imageset

2) add rolodex-image-set-0.1.jar and gwt-rolodex-gwt15-1.1.jar to Guvnor's build.xml

3) some manual code now:
   modify properties / run 'ant plug-editors'
   guvnor-editors.properties
   rules-new-menu.properties

4) add <inherits name="org.drools.guvnor.ImageSet"/> to Guvnor.gwt.xml

5) run 'ant gwt-compile'

6) add rolodex-image-set-0.1.jar to Guvnor's pom.xml

    <dependency>
      <groupId>org.drools.guvnor</groupId>
      <artifactId>rolodex-image-set</artifactId>
      <version>0.1</version>
    </dependency>

7) install the new jar
   mvn install:install-file -DgroupId=org.drools.guvnor -DartifactId=rolodex-image-set -Dversion=0.1 -Dpackaging=jar -Dfile=modules/imageset/rolodex-image-set-0.1.jar

8) build Guvnor
   mvn -DskipTests clean install

9) deploy

That's it!
