Configurable default settings

It would be useful if the following options could be set in a config file: - `@noapprox` on/off - `@plain_number` on/off - Default decimal places for certain outputs (e.g. 2 places for currency) - Default date format (e.g. `DD/MM/YYYY`, `DD-MM-YYYY`, `YYYY/MM/DD`, `MM-DD-YYYY`) This would reduce the need to repeat attributes and formatting in every query.
