add plugin configuration for "[email protected]"

This PR adds support for react-native-gesture-handler.

https://kmagiera.github.io/react-native-gesture-handler/docs/getting-started.html

Android requires additional code change on the delegate level once the package is added. This can be added inside a new delegate inside ern-navigation-impl

Close #115
The proposed solution in the above PR with replaceInFile can be dangerous as it changes the behavior of the base code and there is no easy way to make sure the file does not have compilation issues after the change. Also, if a plugin makes a change to the base file it can have an undesirable impact on other apps/components that do not intend to use this plugin. Please see the Readme section to see how the root view creation can be overridden.

If you wish to test it locally.

• ern cauldron repo add local-cauldron /Code/local-cauldron
• ern cauldron add native app test:android:1000.0.0
• add a config/default.json

  "manifest": {
    "override": {
      "url": "<usr>/Code/electrode-native-manifest",
      "type": "partial"
    }
  }
}

• After that any new plugin config you add to manifest and can test locally, you can use your local cauldron/manifest.
• Sample Mini-App
  ern create miniapp TestGesture
• Add the plugin you want to use locally
  ern add react-native-gesture-handler
• Lastly
  ern run-android

Could you just add a README.md file in react-native-gesture-handler_v1.4.1+ directory (as I did for realm plugin for example).
You don't have to create a demo MiniApp as I did, but just give specific instructions on what extra steps are needed to get this plugin working. We should do this for any native module that require additional steps after running ern add, otherwise users using this plugin will have no idea why it's not working and how to make it work (unless they dig into the PR that introduced the plugin and look at your comment).
If we start having more native modules with extra steps (listed in an README.md of plugin directory) we could also even easily have ern detect that the directory contains a README.md and let the user know after running ern add ... that the plugin need extra steps and log a link to the readme (or even print it in console).

Also - Did this PR supersede and close #115?

Yes, it does.

Yeah no worries.. I wish GitHub would somehow make it visible in the PR "Review in progress". ;)
