these files somehow change, todo: rebase
define basic grammar to parse first two properties...
+hvalues can include further propertylists(->objects)
add array of names
add integer lists, so we can parse incl. globaldata section
well, there is a country called ---
numbers can be keys/property names too
+string lists (parses the unplayed scenario, still fails for later save game)
+rule for object list as object, works for tested scenarios
