"FreeBoard", re-using a lot of Board logic, but with SVG (empty) board + SVG (empty) reserves.
Will be used for variants with custom non-rectangular board (Hex, at least)
Or, with other board shapes (see greenchess.net for example)
+
+Would be nice to display some better variants names (Pacosako -> Paco-Ŝako etc),
+but the "formatted" name with uppercase + all lower cases would still be required.
+(For example in variants list, or tournament variant field).
