Allow customer refund entries from customer credits

Hi,

At the moment, you cannot refund customer credits via cash/credit card or other payment channels, from Sale>Search>Customer/Credits. To do that, you need to issue an invoice, consume the credit, issue another credit note to reverse the invoice, and put the refund entry there. This is just white noise with needless disruptions, i.e. whether you have to/want to disturb tax ledgers, etc. Please simplify this process.
