Gjallarhorn

Replaces the archer with the Gjallarhorn (Hraesveglur ornament) from Destiny 2

PATCH NOTES:

• 2.0 - FIXED TEXTURES

I've spent a lot of effort on this one, custom LoDs, custom-ish animations, repositioned to look right, custom reticle, the only thing i didn't do was a custom reload animation, because the model shattered when i tried to add bones.
