Improve Guise Mummy phase notifications.
Provide better information for Guise Mummy phases.
In addition to the beginning command display, log an info message when starting each phase.
Display a "Done." message or similar when finished.
I've added log messages for the phases, as well as a "Done" notification at the end. The "Done" looks nice, but I'm still not sure whether I like the phase notification.
We can remove it easily enough in the future. I'll use it for a while and see what I think. For the moment we can mark this as "experimental".
