v3.1.0

Fixed improved alt text for real real!
Due to a bug in FixPhotoMetadata it wasn't working despite everything being 'technically correct'. It's now worked around with this version :)

Added GalleVR auto-tagging!
GalleVR has built in support for auto-tagging Resonite photos, I was just accidentally sending the player metadata VRChat style :'D
Now that I'm using the right format, auto-tagging is working :D
