Make it so that AlertDialog.Builder.SetOnCancelListener accepts a delegate/lambda

[WashingtonARamos]

Android.Support.V7.App.AlertDialog.Builder has 4 interesting methods: SetPositiveButton(string, EventHandler<DialogClickEventArgs>), SetNeutralButton(string, EventHandler<DialogClickEventArgs>), SetNegativeButton(string, EventHandler<DialogClickEventArgs>) and SetOnCancelListener(IDialogInterfaceOnCancelListener). While the first 3 make it easy for the developer to set an action for the user input (I can just say SetPositiveButton("Confirm", delegate { MyAction(); }), the fourth one requires the developer to create a class that implements IDialogInterfaceOnCancelListener and implement just this one method OnCancel(IDialogInterface). It would be very helpful if we could do with SetOnCancelListener the same that we do with the others, that being just setting a delegate as the action, for example SetOnCancelListener(delegate { MyAction(); }).
