Money version 4.3.0

Enhancements

• Adds a Money backend in the same spirit as other libraries that leverge ex_cldr. Thanks to @LostKobrakai. Closes #108. All of the functions in the Money module may also be called on a backend module <backend>.Money.fun without having to specify a backend module since this is implicit.

Bug Fixes

• Money.new!/3 replaces Money.new!/2 to accept options. Thanks to @LostKobrakai. Closes #109.
