The Redo Button: Redo Last Undo

The Redo button in the Modify Menu will redo the last undone operation performed with Undo. This can also be accomplished by holding the Shift key and pressing the Tab key. Each undone operation is added to an internal list for possible redo. This list is cleared after any database-modifying operation which is not an undo.

When Xic is waiting for text input to the prompt line, the Undo and Redo commands are disabled.
