 ** Theme magic
 Let's automatically update terminals on theme change (as long as ~pywal~ is available).

+Unfortunately, as the theme is set on startup this causes the hook to be run
+immediately. It would be nicer to /not/ have this add to our precious startup
+time (around 0.4s last time I checked).
+We can achieve this by deferring it with a short idle timer that should add the
+hook /just after/ initialisation.
