  * grant the new ultimateGearSets achievement for existing users' collected equipment

+ *
+ * Changed by Alys on 20150620 to assign false values to
+ * 'achievements.ultimateGearSets' when true values are not appropriate,
+ * because of https://github.com/HabitRPG/habitrpg/issues/5427
+ *
+ * Minimal changes were made so the code isn't as efficient or clean
+ * as it could be, but it's (hopefully) one-use-only and minimal changes
+ * means minimal new testing.
