rbutil: improve voice and talk generation.

- introduce a talkgenerator to better share code between voice and talk generation.
- name intermediate .talkfiles after the md5sum of the text. (prevents naming problems).
- do not directly use the logger, instead emit signals.
- move talkfile and voicefile generation to base/
