Added one BroadcastListener that listens for TextToSpeech.Engine.ACTION_TTS_DATA_INSTALLED intents.
If it gets one, it will call TextToSpeech.Engine.ACTION_CHECK_TTS_DATA to update list of TTS voices.
It expects TTS engine to broadcast TTS_DATA_INSTALLED also when removing voice data.
In order to catch changes done when user sits in Text-to-speech output main activity,
TextToSpeech.Engine.ACTION_CHECK_TTS_DATA is called on start of tts engine config fragment.

The spec does not specify case sensitivity and support
for 3 letter locales is currently poor.

This is required to fix the case where an app has instantiated
and is using a TextToSpeech instance, and the user switches to
settings and changes the language for that instance. If no
app was using TTS, then onCreate() would have be called when
TTS is used next, and the correct locale will be loaded.

(a) The TTS API doesn't mandate that unavailable voices should
be set and null, so deal with it correctly.
(b) The android manifest contained a reference to the old
TTS class.
