message: Adds PayID-Version header to PayIDClient
  This hardcodes the `PayID-Version` header to be `1.0`, per the breaking changes in As is, `xpring-js` does not work for `PayID` `1.0.0` (because it doesn't pass `PayID-Version`) and it does not work for `PayID` `0.1.0` (because it expects to get back an array of `addresses`).
