Notify of pokes and private messages on Android, with TeamSpeak's sounds

While the app is out of sight, a poke or a private message posts a
notification; a message's one gathers the conversation, takes a reply
inline and opens its chat. The notifications are silent, as the sound
pack already plays TeamSpeak's own sound for either.

The build bundles the sound packs of the TeamSpeak 3 client found next
to the checkout (or at ts3.client.dir / TS3_CLIENT_DIR), unpacked into
the profile once per app version. Sound Settings picks the pack and its
volume, and speech packs talk through the phone's text-to-speech.
