convert eyepatches and masks from headAccessory to eyewear - fixes https://github.com/HabitRPG/habitrpg/issues/3645

@lefnire This requires `migrations/20140829_change_headAccessory_to_eyewear.js` to be run. Note the comment saying "UNCOMMENT ONE OF THESE LINES"

Goes along with https://github.com/HabitRPG/habitrpg-shared/pull/291

- modifies code to treat eyepatches and wondercon masks as new eyewear gear type instead of headAccessory
- updates database_reports/count_users_who_own_specified_gear.js since that reports on wondercon masks
