NodeType include relationshiptype info in state representation

[ahonor]

Include the relationship type information to the state representation output.

Here's an example showing tags used by the XML import format. It shows two node type relationships for this Nodetype:

<nodetypes>
   <nodetype id="1" name="Node" description="An application host" image="Node.png">
      <templateAttributes>
         <templateAttribute id="1" attributeName="hostname" attributeId="14" nodetypeId="1" required="false"/>
      </templateAttributes>
      <nodetyperelationships>
         <nodetyperelationship rolename="environment" parent="Site" child="Node"/>
         <nodetyperelationship rolename="packages" parent="Node" child="Package"/>
      </nodetyperelationships>
   </nodetype>
</nodetypes>
