Similar as done with SAPI / MSSP make the current implementation for executable based TTS engines a base class and create derived classes for each supported TTS. Removes the need for the implementation to know about the individual TTS engines. Add support for speaking directly (i.e. without going through a temporary wave file, currently only used by espeak).
