fixed issue where an incident's related threat actors were not being printed out -- the row showed up, but the details sell contained no data, whereas it should have a expandable link for that TA
updated the xslt templates for Description elements to work with both the default mode and the cyboxProperties mode (previously it was just the cyboxProperties mode).

also changed the description template to apply templates to its child text (needed for the html5 formatting rules to apply)

this fixes the issue where top level items' html5 descriptions were not being properly formatted as html5 text
