Implement Heal Bell, Aromatherapy, Sparkly Swirl and added status effect options to overrides

[innerthunder]

This is a cleaner version of my last pull request...

A new attribute HealPartyStatusAttr implements the status healing effects of these moves:

• Aromatherapy
• Heal Bell
• Sparkly Swirl

These moves are also implemented/updated with the existing HealStatusEffectAttr attribute:

• Purify
• Refresh (should now wake up the user if used via Sleep Talk)

New overrides are also added to overrides.ts. STATUS_OVERRIDE initalizes player Pokemon with the specified status effect, and OPP_STATUS_OVERRIDE does the same for enemy Pokemon.
