WordCamp Budgets Dashboard: Centralize currency conversion and formatting.

These will be used by upcoming modules in addition to the current one.

Note that escaping was removed from format_amount(), since that should be done as late as possible.

wp_kses() is performant in this situation. See ​https://www.tollmanz.com/wp-kses-performance/
