The ModalEnforcerMorph gives the ability to make any set of Morphs (and their submorphs) be modal to the rest of the World. Improves on the standard scheme for doing modality in a variety of ways. Most importantly, only the modal morphs can recieve mouse and keyboard events, so you can't click on another system window and bring it in front of a modal morph that is hogging the keyboard.
A ModalDialog subclass of SystemWindow is provided, with some example dialogs (message, confirm, yes/no/cancel).
