- Before, the Input/OutputStream classes handled Streamables directly
and Streamers were never created for them. Simplified the code somewhat
by always creating a Streamer. It's now more like the Java side, too.
- No more BAD_STREAMER, since null now means "bad".
- Built-in support for streaming enums.
