Version 8.0.5

Patch

• Updated dependencies.
• Handle invalid types in multipart fields and respond with meaningful HTTP 400 errors, via #139:
  • Invalid operations type.
  • Invalid map type.
  • Invalid map entry type.
  • Invalid map entry array item type.
• Additionally test current Node.js v8 and v10 versions with Travis.
• Reduced the size of the published package.json by moving dev tool config to files. This also prevents editor extensions such as Prettier and ESLint from detecting config and attempting to operate when opening package files installed in node_modules.
• Removed the watch dev dependency and watch script.
• Simplified the prepublishOnly script.
• Change to the classic TAP reporter for tests.
• Add apollo-server-koa and apollo-server-express back to the compatible environments list in the readme, now that they use the current version of this package.
