I should be able to confirm a QLButton

(User Story, To be Fixed , Priority: Critical, Test Status: No automated tests yet , Reported By Justin du Coeur, )
Functions, User Interface
Summary: That is, I should be able to specify a message that will be displayed when I press the button; if I press the button again, it will take effect.
This is so that I can implement "delete" properly with a _QLButton.
