Makes a group jaunt spell

Created by: clusterfack

1. Adds invocation to jaunt and group jaunt
2. Creates an adminbus group jaunt spell, gives everyone jaunting for double the time of regular jaunt with a double cooldown as well in a 3 tile range
3. Group jaunting makes an image so all jaunters can see each other
4. Group jaunt adminbus only and maybe will be placed on a secret map or away mission or vault some day so it requires no robes
