Sets the defaults as follows:
 * The start date is set to now.
 * The title is set to the short title.
 * If there is no CP coordinator and there is exactly one site with a coordinator, then the
   default CP coordinator is the site coordinator.
 * If there is no CP site and there is exactly one coordinator site, then the default CP site
   is the coordinator site.
