Add version and data directory to initdb output

Hackers,

initdb is already pretty chatty, and the version of the cluster being
installed seems useful to include as well. The data directory is probably
less so - though I am thinking that the absolute path would be useful to
report, especially when a relative path is specified (I didn't figure that
part out yet, figured I'd get the idea approved before working out how to
make it happen).

Moving "Success" to that "summary output" line and leaving the optional
shell command line just be the shell command made sense to me.
