[RFR] Split settings config

[mattboon]

@artibella adds setting and translation helpers.

import { setting } from 'settings';
import { translation } from 'settings';

setting('dateFormat');
translation('homePage.modal.button');

Huge job to retrofit them into all the places we use settings.x though.

Or do you think it should be split even more?

import { translation } from 'translations';
