Implemented by controls/classes that need to react to a change in a
transaction's state. Typically, controls like status bar and navigation bar
need to update their display with a dirty flag/button that indicates whether
the ensuing transaction is clean or not. Those classes can implement this
interface and add themselves to the DCApplication's transaction state listener's list
so that they get notified of the change.
Invoked when the transaction is either marked dirty or clean.
