Add tracker and display for all slayer drops

Added token and 20% chance slayer drops. Also added display for the slayer tracker with /display.

This was more difficult than I thought. I first tried to use the PlayerEvent.ItemPickupEvent event, but it was server side only. Then I tried to use the ClientChatReceivedEvent event, but the boss slain message was sent to late. Ultimately, I decided on the PlaySoundEvent event, which waits for the noise for when a slayer boss dies.
