Autogenerate files for a React gateway status/config page

[grossm04]

Right now, you have to locate some src/main/javascript boilerplate files from another project, copy them in, and spend some time fiddling with them. And then you have to modify GatewayHook to use the correct built .js file. At the least, it would be nice to autogenerate a skeleton.jsx file, the index.js and model.js files, and any other needed files (package.json, webpack.config.js, etc).

Definitely something I'd like to do, but will likely occur after (or with) adding support for perspective project generation, which itself is blocked on some internal work to update project structures and define best practice layout and toolchains.
