1.0.0-alpha8

Prepping to launch first big website on Gatsby 1.0.0! Knocking out some remaining bugs.

Added

• Extension API swOnUpdated for when a service worker finishes
  updating. Use this to alert users of your app to reload to see the
  latest version.
  commit

Fixed

• hot reloading now fully works. Apparently you can't use function
  components for top-level routes on react-router with react-hot-loader
  3.0 ¯\_(ツ)_/¯ #532 and
  commit
• Webpack needs the help of an obscure setting recordsPath to preserve
  module ids across builds. Big thanks to @NekR, @bebraw, and @TheLarkInn for helping me with this. Previous to this change, loading changed JS chunks could cause a JS
  error as the module ids the new chunk expects wouldn't match the module
  ids from the older chunks.
  #533

Changed

• Disabled hard-source-webpack-plugin. It speeds up builds significantly
  but has been causing hard-to-debug errors while developing. We'll
  circle back to it down the road.
  commit
• Restored using ChunkManifestPlugin. It was disabled while trying to
  debug the mismatched module id bug but that being fixed, we're using
  it again.
  commit
• Name modules ids in development for easier debugging. Primary benefit
  is you can see which modules are getting hot reloaded.
