Add mbrowrap.cpp to emulate the mbrola library which is available in Windows, but not on Linux.  mbrola voices in command-line espeak and libespeak now call mbrola directly rather than generating phoneme information as text.  Mbrola phonemes as text is still available with the new --pho command-line option.
