* Lock bs-platform to 5.0.3 (avoiding issues with reason language server)
https://github.com/jaredly/reason-language-server/issues/275
* Reformat code
* Ask bucklescript to use es6 instead of commonjs
* Rework getInitialProps (can now use a promise)
* Ignore .bsb.lock
With this setup we're compiling the .re/.ml files directly to source
directories with a .bs.js extension, and enabling next.js to pick up
that extension for pages.
