Select Escape button result of MetroDialog.

Feature request: allow the caller to select the default "Escape" / cancel action.
At the moment, pressing Escape will always set the result to Negative (or Affirmative, if that is the only option).

However, in my typical Save dialog (Yes / No / Cancel) I would prefer to have the FirstAuxiliary action as the cancel action. It would be nice if I can pass this in through the MetroDialogSettings.

Cool, thanks. Was a bit of a wait but glad you managed to include this!
