Added a launcher for the Slack chrome app.
Disable Compiz window previews (thumbnails) because they don't work with per-monitor panels.
Update setup display script so it can be used to reset when compiz is running, if I do anything silly. Also make it fix the per-monitor panels.
Make the per-monitor characters slightly thicker to suit the font; main deskbar panel back to listing all of the workspaces.
Draft scripts for tmux things.
