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).

Support retrieving the vendor name of the TTS. This will be used by TTS string
corrections. Currently no other TTS but SAPI supports this, and only correction
strings for SAPI voices depend on the vendor information.

The current TTS configuration doesn't allow querying the system values so it
currently can't be displayed. A value of 0 will use the system default. The
default pitch is dependent on the voice; most voices should have a default
pitch of 45 - 55.

Note that some voices don't support speed adjustment. These voices will ignore
the selected value. The current implementation doesn't mark those voices in any
way.

This adds basic support for using the OS X' TTS system. The current
implementation does only support selecting the voice itself, no further
settings (like speed pitch / speed) adjustments are implemented. As OS X' TTS
system wants the strings to get spoken in 8 bit encoding problems with locale
combinations are possible. For this better error handling in the rbutil TTS is
needed. The voice test button in the configuration dialog reacts pretty slow
due to the way its speaking is done. This can get changed but also requires
adjustments in the rbutil TTS system.
