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).

MSSP is accessible via vbs by simply changing the object to be used (both
SAPI5 and MSSP use the ISpVoice COM interface). Add command line parameter to
sapi_voice.vbs to switch the COM object used, and add the necessary
implementation of the SAPI class to Rockbox Utility.
Important: you will need to install the Speech Runtime separately and install
the version matching the bitsize of Rockbox Utility. I.e. you will need to
install the x86 version even on a x64 machine (unless you build a 64bit binary
of Rockbox Utility).

Based on the previous change add a derived class for SAPI4 support. Note that
SAPI4 support had been disabled, so it's also disabled to not show in the
selection dialog for now.

On Windows espeak installs itself as command line program as well as as SAPI
voice. Using the SAPI voice is simpler, so there is no need to keep the command
line option for it.

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.
