Spencer Elliott c1faabcdf6 Replace applescript with https://github.com/sindresorhus/opn
Summary: This allows opening the Chrome debugger on OS X, Linux, and Windows, and succeeds the previous PR which used [browser-launcher2](https://github.com/benderjs/browser-launcher2) and included a `--dangerouslyDisableChromeDebuggerWebSecurity` option: https://github.com/facebook/react-native/pull/2406

[opn](https://github.com/sindresorhus/opn) is cross-platform and much simpler than browser-launcher2 (since we don't have to manage the opened Chrome instance; the OS will just use the default instance).
Closes https://github.com/facebook/react-native/pull/3394
