Get payload by Custom Identifier (#9)
* Added Payload Details to the Server App * Added GetByCustomIdentifierAsync to the XummPayloadClient. Input field has been added to the SignIn flow in the Server App to provide a Custom Identifier which can be used at the Details page to retrieve the payload details.
