Fix Music cape requirments for random events

[nwjgit]

Description:

Currently music cape requires 1 of each random event, only a handful of random events provide a unique track. A previous update changed how these tracks are unlocked: "All unique random event music tracks are unlocked the first time you enter a random event that has its own unique music track."

Changes:

• Add uniqueMusic?: boolean; to random events with unique music tracks
• Update music cape requirement for random events
• A few punctuation corrections

Other checks:

• I have tested all my changes thoroughly.
