Enable TC by default and hide

Set up TC so that it is always enabled and defaults to realtime mode.

This allows us to have warp-like functionality without showing
the TC interface, and simplifies a lot of tutorials.  We can still
reconfigure the TC by re-installing the plugin with different settings
