bootstrap.sh: allow explicit overwriting the current installation profile

Also, if the user attempts to install a profile which is already there,
now the scripts exits instead of just printing a message and carrying
on.

The previous lazy behavior could result in some confusion if the user
didn't see the message, because any different settings in the specified
profile would not be picked up, as the previous profile already in
web/profiles/ would be used.
