Include name of nearest town (if applicable) in memorial file.

Shows the name of the town you were in when you died, plus or minus some inaccuracy as towns don't evenly spread from the intersection that starts town generation. Examples:

* He was killed in a liquor store in Framingham.
* She was killed in a house on the outskirts of Medford.
* He was killed in a fungal bloom in the wilderness.

Yes; towns have names! But until now, they were completely invisible. I hope to follow this up by showing the name of the town on the map while you scroll around, but that'll be another PR.

PS: Jenkins is going to say this fails to build; ignore it, Jenkins is b0rked at the moment.
