More Variables for E-Mail Notification-Templates

Right now there are {channel_name}, {entry_title}, {entry_url}, {comment_url}, {cp_edit_entry_url}, {name} and {email}.

It would be great if there would also be a{entry_date} (the currently proposed Entry-Date) and maybe some of the data from the variables above but splited out … like {entry_id} or {url_title} and stuff.
