Adjust the banner we print after "make install":

1. Make sure the user _first_ edits or at least reviews
   the config files and _then_ tries to fire up Apache.  (This is IMHO
   important because we know of problems like "Group #-1" which currently lead
   to a "Haha...  immediately fire it up. Good joke" by the users)
2. Compactify it a little bit.
