Investigate spawning scripts with a shell

[todbot]

Currently Blink1Control2 doesn't spawn a shell when executing scripts. This could lead to confusion for users finding that running scripts on the command-line works one way and differently when run by Blink1Control2.

It looks like Nodejs provides a way of running with a shell: See: https://nodejs.org/api/child_process.html#child_process_child_process_spawn_command_args_options and even a way to specify which shell to run with. This could end up being more confusing than it's worth, but it warrants being looked into.
