Update lint style for Standard@9.0.0 - first patch

Fix #7492

This PR addressed the following new rules:

no-multiple-empty-lines
no-useless-return
generator-star-spacing
padded-blocks

Test plan (two steps):

1. With current standard, run

npm run lint

• There should be no linting errors

2. Update standard@9.0.0

• Lint errors should not include:
  • Too many blank lines at the end of file...
  • Unnecessary return statement
  • Expected indentation of...
  • Missing space after *
  • Block must not be padded by blank lines

Note: Most files were updated running standard --fix. Below files that were updated manually:

main.js (code commented as a reference)
settings.js
dataFile.js

We're going to want to bump up the version of standard in the package.json also

[cezaraugusto]

if we bump now there will be several lint errors that are still unfixed by this PR. Plan is doing changes based on a group of rules, and only update standard when all new rules are properly lint.

That sounds good :)
