Update sr.alias

[Lathaon]

What Alias/Snippet is this for?

!sr

Summary

Update !sr

• Fix !sr not working in direct messages
• Fix error in maxed rolls with Durable and Verdan
• Stop Song of Rest applying to 2024 Bards
• Stop 2014 Durable applying to 2024 characters
• Add support for Boon of Bountiful Health (FR: Heroes of Faerun)
• Add support for Bloodlust (Astarion's Book of Hungers)

IMPORTANT: !hd and docs will still need updating (honestly I'm surprised there isn't a library for this collection) but hopefully that'll be easy enough now that I've done this part.
