Gert Pellin - GPE 471478868d cadcraft-cli: --help / -h / help exit 0 and print the usage to stdout (#1526)
A help request is not a failure: --version already goes to stdout with
exit 0, and now --help, -h and help do the same. Bare cadcraft-cli
keeps reporting on stderr with exit 1, like git.

Fixes #1525
