Enable using built-in chatboxv0.3

VRChat exposes a built-in chatbox which can be seen by anyone who has
it enabled. This was not the case when I started this project: the
chatbox would only be visible to friends. Since this is clearly useful,
enabling the STT on public models, let's enable sending data to it.

Caveats:

* The built-in chatbox has anti-spam tech which limits us to updating
  about once every 2 seconds. The custom chatbox has no such limitation
  and is thus typically much faster.
