Make sentence options (Capitalize and full stop.) work, and handle inbound messages as advertised.

NB Hariz Kouzinopoulos: I did not use your patch, because while it is technically correct, the job of saving the widgets' values is performed automatically by KCAutoConfigModule, if it knows about the widgets. A previous author neglected to change the widgets passed to KCAutoConfigModule when adding the sentence options, so that is why these were not read/written. Thank you for submitting a patch though, it was the impetus to solve the bug properly.
