TSlint is legacy, eslint is the future/

• Run the following:

npm uninstall tslint tslint-config-semistandard npm install --save-dev eslint-plugin-promise eslint-plugin-standard eslint-plugin-node eslint-plugin-import npm install --save-dev eslint-config-standard eslint-config-semistandard @typescript-eslint/eslint-plugin eslint @typescript-eslint/parser

• Copy over .eslintignore & .eslintrc from Zenobia
• Copy the "lint" and "fix" tasks from Zenoba
• Remove tsconfig.lint.json
• Now, apply linting changes.
