API - woocommerce_currency should return separate field for symbol

[belcherj]

When using the wc-api to get general settings /wc/v2/settings/general, the woocommerce_currency object has an options array that has the following format:

{AED: "United Arab Emirates dirham (د.إ)"}

This results in having to use a regex to separate the country and currency name from the currency symbol.

I propose that the options object should take this format:

{ AED: { country: "United Arab Emirates", currency: "dirham", symbol: "د.إ" } }
