SAPI and NSSS word events

[willwade]

If you run

import pyttsx3
def onStart(name):
   print('starting', name)
def onWord(name, location, length):
   print('word', name, location, length)
def onEnd(name, completed):
   print('finishing', name, completed)
engine = pyttsx3.init()
engine.connect('started-utterance', onStart)
engine.connect('started-word', onWord)
engine.connect('finished-utterance', onEnd)
engine.say('The quick brown fox jumped over the lazy dog.')
engine.runAndWait()

on SAPI it was still broken. Im not sure how - but I think one of the PRs cancelled out our changes. Nay mind this PR is better now as we now get

starting None
word The 0 3
word quick 4 5
word brown 10 5
word fox 16 3
word jumped 20 6
word over 27 4
word the 32 3
word lazy 36 4
word dog. 41 4
finishing None True

This works on SAPI and NSSS (NB: It already worked on espeak)
