Add a few words to the context's default dictionary
Work on code-to-words a bit more to include more punct.

It's still not the correct way to generate the mapping,
as the *user*'s preference should be used, not *mine*
to decide how to say "dot" or "open brace"... basically
they should be the ones deciding how to speak those phrases,
but we need a default for out-of-box behaviour.
