Title: Fix: runner path issue, handle tmux not running

### Runner path issue

If you set the default-path option for tmux, new panes won't be in the correct directory. To fix this, you cd to vim's working directory when a new pane is created.

### Handle not being in a tmux session

If you run a command outside of tmux (maybe by accident) it explodes with output. To fix, you check the $TMUX environment variable and throw an exception if you aren't in a tmux session.
