Reduce the number of files published to npm for a plugin

[chasenlehara]

I believe the following files & folders can be removed when a plugin is published to npm:

• .editorconfig
• .jshintrc
• .npmignore
• .travis.yml
• build.js
• documentjs.json
• test

Here’s the file where these can be added: https://github.com/donejs/generator-donejs/blob/a50d2851bf788ec11473b49e9c8b46a1eff4bd82/plugin/templates/static/.npmignore

Some popular projects use the package.json "files" field instead. We can get rid of the .npmignore and use:

{
  "files": ["src", "dist"] // to only include the code
}

I also looked up some discussion on tests and documentation and whether to exclude them. The consensus seems to lean towards being as lean as possible.

After reading the docs on files and npmignore, I think it’d be better for us to have a whitelist of files to publish rather than a blacklist of files to exclude.
