A stable string key naming one cell, for Map/Set membership.
'x,y' is the spelling consumers reach for anyway (the Wesnoth port keys its own Maps by
hand with it); taking it from the framework means a key written by one system is understood
by the next, which a pair of numbers in a string is otherwise not guaranteed to be. Negative
coordinates are included, since a grid view that scrolls can hand one out.
