Subject: [PATCH] close #5, close #16: add money-related Settings

Also:
- adds some missing Bootstrap variables/configs, needed for a more complex form such as the Settings page
- adds a LOT of options to Linput - affixes, size, fullWidth, help prop/slot, and plainText (see https://github.com/bestguy/sveltestrap/issues/582)
