Disconnect from window user time notifications, only sort when mapped
Before we were badly leaking AppIcons by not disconnecting from the
window signal handlers when our actor got destroyed. This caused
us to repeatedly re-sort the windows for each AppIcon that
had ever been displayed with obvious bad consequences.
Besides simply chaining the signals to the lifetime of the AppIcon
actor, we also only do the sorting if we're mapped. This decreases
the amount of work to do in the not-mapped case.
