Replacing the short app name on the delete application page with the full application url to help negate confusion when deleting applications when you have access to multiple domains.  
php-testing.example.com instead of just php  
Similar to how github does it when you delete a repository, they show the user or organization name plus the repo name.  if this format is not appropriate, let me know what format would make more sense maybe domain/app_name?
Use @application.domain_name instead of domain_id,  they are aliased today, but just in case that were ever to change we would want the name to be used for display purposes
