Assembly file fixes
- using "jboss-as7.0" in the <id> element
  leads to the <type> of the dependency being "0.war" instead of war.
  For example:

<dependency>
  <groupId>org.jbpm.dashboard</groupId>
  <artifactId>jbpm-dashboard-distributions</artifactId>
  <version>6.0.0.Beta5</version>
  <classifier>jboss-as7</classifier>
  <type>0.war</type>
</dependency>
