Navigate to a Person's Rooms and last known location

Closes #218

• rubocop -A
• Formulate vision for the feature in advance, just like Kent Beck would want it
• Implement feature, perfectly matching what I set out to do in the tests (naturally)

I couldn't really get the "Directions" buttons to float / justify / align to the right completely, maybe some CSS guru here has an idea? If not, I think it looks okay enough right now

Ah, in all of my testing, I never noticed that we apparently removed navigating to coordinates at some point? This of course disallows inputting a person's coordinates too. I don't really see why we wouldn't allow coordinates, so should it just be added back in? (in a separate PR, possibly by someone else, that is)
