Title: 427 warn user about erasing new talk info

Added a flag indicating whether or not all input fields are enabled.
Added a function confirm_add, which is called when the "Add New Talk" button is clicked. If the Title, Presenter or Description fields contain text, a dialog box will request confirmation.
