Modifyable launchers

[Maciej Kisielewski]

Hey Jeff!

I remember your bug on the same topic[1], replied there.

Shebangs used with checkbox-cli are used as a shortcut for explicit
checkbox-cli invocation with a launcher arg. checkbox-cli is not an
interpreter, it uses stdin for interaction.

I can see that feature, provided that :
 - stdin is not a tty
 - launcher is piped in
 - and ui is non-interactive

For now, I recommend using intermediate launcher file, and invoking that
file.
