Update archetype jboss-spring-mvc-archetype to reference correct versions from EAP 6.1.0 maven repository

Use the archetype org.jboss.spring.archetypes:jboss-spring-mvc-archetype:1.0.0.Final to generate a project, set enterprise property to true.
The versions in generated pom.xml should be aligned for use with WFK 2.3.0 and EAP 6.1.0 maven repositories.

change version of com.redhat.jboss.wfk.boms:spring-3.2-bom to 2.3.0-redhat-1,
change version of org.jboss.bom:jboss-javaee-6.0-with-hibernate to 1.0.4.Final-redhat-wfk-2
add dependency (either to <dependency> or <dependencyManagement> section):

        <dependency>
            <groupId>dom4j</groupId>
            <artifactId>dom4j</artifactId>
            <version>1.6.1-redhat-5</version>
        </dependency>

The pom.xml also defines property `version.spring` (with value 3.2.2.RELEASE) that is never used (the Spring Framework version is specified by Spring-3.2 BOM).
