Wrap lines at 80 columns where appropriate and I had the energy to think
about how/where to wrap.
There are still lines longer than that, which I plan to wrap in the
future. But that is enough for now.
When restarting i3 check for connected second monitor: scale it and
restart polybar if there is one.
Put polybar tray on the main monitor.
Do not kill polybar and relaunch it when restarting i3, but restart it
using ipc (much faster).
