fixed display of the following fields on Incident:
 * time (was only showing Incident_Reported time before; now using cyboxProperties styling to show all children)
 * external id (was not displayed before)
 * victim (broken previously, such that it was not being displayed)
 * affected assets (now display with cyboxProperties styling -- before it was just using the default xsl template and showing all text)
add stixCommon:Identity|ta:Identity
added support for incident:Victim to be printed via cyboxProperties-style output
