Lines 41 to 50 in 82fcfa3

	enum ActionCommandDifficulty {
	AC_DIFFICULTY_0 = 0, // easiest
	AC_DIFFICULTY_1 = 1, // very easy
	AC_DIFFICULTY_2 = 2, // easy
	AC_DIFFICULTY_3 = 3, // standard
	AC_DIFFICULTY_4 = 4, // harder
	AC_DIFFICULTY_5 = 5, // hard
	AC_DIFFICULTY_6 = 6, // very hard
	AC_DIFFICULTY_7 = 7, // hardest
	};

This enum should have members like AC_DIFFICULTY_EASIEST, AC_DIFFICULTY_VERY_EASY, etc. instead of having the actual difficulty appear in a comment. Also, the values (= 0 etc.) can be removed since incrementing by one per member is the C default.
