Template out of date

[agg23]

This template needs to be adapted to support the latest version of react-nodegui and nodegui itself at any point in time, or otherwise indicate to users that it may not be up to date. Additionally, this repo stores the entirety of react-nodegui-starter, which should be added as a submodule.

I spent a good while debugging styling issues before realizing that I wasn't running on the latest releases, which was very unexpected.
