[Seaside] A simple request for my future students

[stephane ducasse]

hi Avi

would it be possible to get a better error message than "error "
when we try seaside for the first time and we naively type 
http://localhost:9090/seaside/
and not http://localhost:9090/seaside/config or counter.

I followed stupidly the steps explained on the www.seaside.st and 
(after guessing with
versions of the packages and replying no to an old dependency) I got 
the error
and I forgot (because my brain is too small) that!

So could it be possible/make sense to have a error message for dummies 
like me

seaside reports an error. Have you tried /seaside/config?

or Seaside Error: There is no application running there. Have you tried 
/seaside/config?

You see a stupid stuff to lower the entrance....for newbies.
