Voicefile generation: implement string corrections.

Voicefile generation now can correct strings for the TTS system similar
to what voice.pl does. The current implementation has some limitations:
- only implemented for voicefile creation.
- the corrections file is built in and can't get changed.
- string corrections can be disabled in the configuration dialog.
