updated the registry key custom template to remove the "Location" table header cell
now pulling out cybox relationship label for cybox:Related_Object elements

note: this only works for cybox:Related_Object elements that are inline at the moment.

this works:

```xml
<cybox:Related_Object id="123">
  <cybox:Properties xsi:type="...">...</cybox:Properties>
  <cybox:Relationship>...</cybox:Relationship>
</cybo:Related_Object>
```

this does not work yet:
```xml
<cybox:Related_Object idref="123">
  <cybox:Relationship>...</cybox:Relationship>
</cybo:Related_Object>
```

(also have a bit of debugging code in here that is needed until this issue is resolved)
cybox:Related_Object contents should now be properly handled -- 1) the data is correctly normalized in preprocessing, and 2) the relationship labels are correctly maintained and displayed in the html output.
