installer --version outputs to stderr.

[nicholaswilde]

When running installer --version, the output is directed to stderr instead of stdout. Also, a return character needs to be added to the end.

Referencing this article.

Expected behavior.

$ ./installer --version
0.2.9
$ ./installer --version 1> out.txt 2> error.txt && cat out.txt
0.2.9
$ ./installer --version 1> out.txt 2> error.txt && cat error.txt
null

Actual behavior.

$ ./installer --version
0.2.9$
$ ./installer --version 1> out.txt 2> error.txt && cat out.txt
null
$ ./installer --version 1> out.txt 2> error.txt && cat error.txt
0.2.9$

Agreed. Should go to stdout. Issue belongs https://github.com/jpillora/opts here though. No idea why I decided on stderr many years ago, trying to think now if this change could break anything...

I appreciate you looking into this.
