Subject: [PATCH] Replace applescript with browser-launcher2

This allows...

1. launching Chrome on platforms other than OS X
2. users to launch their own instance of Chrome (e.g. via command line)
   rather than being forced to use the default instance (i.e.
   `tell application "Chrome"` always used the default instance)

`isDebuggerConnected()` addresses the problem in #510 where the dev tools
would only open once per server session.

Add a '--dangerouslyDisableChromeDebuggerWebSecurity' flag to
packager.js to enable Chrome '--disable-web-security' flag.

This allows users to inspect network requests in Chrome by commenting
the xhr polyfill in InitializeJavaScriptAppEngine.js:
  https://github.com/facebook/react-native/issues/934#issuecomment-94525104

Usage:

    node packager.js --dangerouslyDisableChromeDebuggerWebSecurity

or:

    packager.sh --dangerouslyDisableChromeDebuggerWebSecurity
