Fix a bug with savegames introduced with changeset c7bcc0ec2267.
Warning: savegames created since c7bcc0ec2267 are probably corrupted,
you may have to start the game over.
If you chose not to do so, you should replace all occurrences of 'TextWindow' by 'TextImplWindow',
and 'Text Window' by 'TextImpl Window' in your save files.
