Availability and access have the following different display conditions:
#if(!$model.isDropbox() && ! $model.isSiteCollection())
#if($availability_is_enabled && !$model.isUserSite() && !$model.isDropbox() && ! $model.isSiteCollection())
In MyWorkspace Resources, only access is displayed.
In other sites Resources, access is displayed and availability is only displayed if it's enabled.
Under the title "Availability and Access", whichever way availability is set, we can have different controls available.
If we separate Acces and Availability, we will show the access settings under an "Access" title and we will only show the "Availability" title and settings if availability is enabled and available in the current content model type (UserSite, other Site, ...).
