Title: Merge json refactor

This is a large pull request. It contains 3 things:

1. Fixes for activity engine
2. JSON library change. In production, we saw a decrease in signal latency from about 110 ms to 80 ms!!! as a result of this change. We believe this improvement is enough to power home page on USCP despite USCP's additional overhead above signal's. I think there's actually further improvement that can be made by improving the serialization of SenseiResult.
3. Looks like Volodymyr's sensei-ba stuff sneaked in... we can try excluding that if necessary.
