Upgrade various dependencies to latest part 2 (#1557)

* Upgrade various dependencies to latest, remove unnecessary electron-hunspell
  - upgrade eslint and friends to latest
  - remove deprecated 'node-sass' in favor of 'sass'
  - disable new rules from 'eslint-config-airbnb' that are conflicting with current code style
  - add workspace config for 'vscode' that silences 'experimentalDecorator' warning and forces 'prettier' to single quote
* Run yarn lint to autofix with new ruleset and worked down lint issues to zero
