Feature/71 setup front end linter

[leandertolksdorf]

Done:

• Setup ESLint and .eslintrc.json
• Setup Prettier and .prettierrc
• Lint and format legacy code

Please install the Prettier extension in your IDE and configure it to auto-format on every save. This will ensure a consistent formatting.

You can run the lint script manually with npm run lint

@motschel123 @PhlppKrmr @jandegen I updated the scripts. Now to run eslint: npm run lint || lint:fix, for prettier: npm run prettier || prettier:fix and to run everything: npm run format. The prettier-scripts also run on .svelte files. To configure VSCode to auto-format .svelte files on save, you have to add this to your settings.json:

"[svelte]": {"editor.defaultFormatter": "svelte.svelte-vscode"}
