Add monitoring script to rebuild code after editing

[brayovsky]

Testing the app manually during development is hectic since one has to rebuild after every change. It would be simpler if we had a script to watch for file changes and rebuild. All a developer would have to do then would be to click the restart button on the debugger. A tool like npm-watch or something better.

for sure 👍a watcher would make developing this extension much more pleasant.

@adamwatters What if we 'ejected' the app and then add a plugin like this that can write content generated from webpack-dev-server to disk to webpack config? With this we can:

• Live reload files
• Prevent the browser from starting up when running yarn start since we might not use it.
