Support for streaming for bash commands

[rbren]

Currently you have to wait for a bash command to complete or timeout to see any of the output. It'd be nice to get the progressive output via a stream.

This will be hard, we'll probably need a second websocket or sth

This should be easier with tmux, and can just take a tmux screen output and poll on it periodically

Any progress on this? Looking forward to this feature.
