Is possible to inline geckodriver?

[linux-china]

For beginners, it's still some hard to try. You should install geckodriver command line and FireFox. Firefox is ok for developers and geckodriver is unfamiliar for most developers. Could Scout add geckodriver as dependency and inline geckodriver into Scout.

Stacktrace without geckodriver, not friendly for developers. Is possible to give hint to ask developers to install geckodriver.

Hey @linux-china - yes I think including geckodriver and firefox in the install is a good idea and have always intended to do it, I just haven't decided on the best way to do so. I'm open to suggestions or PRs on this topic
