Update Core.lua

Added more bonus IDs

[Lombra]

If I remember correctly, the only reason this table exists is to be able to store only the item ID rather than the full item string when the bonus ID is irrelevant. I'm starting to wonder whether it really is worth the effort.

Sometimes editing and creating sets ingame is not functional for me, so instead I use RStudio. Bonus IDs are an easy way for me to get the appearance I want since I personally don't always get the right thing with Mod IDs. That said, you make a solid point.
