AcceptDragDropPayload can't be checked for nil

[ptxmac]

AcceptDragDropPayload will return a "nil" Payload if the currently dragged item is not of the expected type. There's currently no way to check this.

Either AcceptDragDropPayload should return a nil object if the payload is nil, or the Payload type should have a way to check for nil

I.e. from the client code:

if AcceptDragDropPayload("Node") != nil {
  // handle drop
}

OR

if !AcceptDragDropPayload("Node").IsNil() {
  // handle drop
}

I can fix it in #229 but I have a problem there so idk when will it get to master...

[ptxmac]

Confirmed as working! 🎉

hreat to hear!
But I accidently removed Payload.Data() 😄 - will fix soon

[ptxmac]

Yeah, that didn't work before for me anyway, so my local hack was just to keep drag data in a global variable 😄

now should work
