There is no ZWL currency

[dkasenka]

Hi guys

I've found out that the library doesn't include ZWL. https://github.com/Rhymond/go-money/blob/master/currency.go#L48

ZWL must replace ZWD according to ISO_4217: https://en.wikipedia.org/wiki/ISO_4217

Please fix it.

Hi

Thanks, you can create PR and include missing currency. Please create a new record in the list to keep backwards compatibility, I think for now we should keep both currencies.

Also ZWD code must be 716 instead of 932 932 is for ZWL
