Minor Change

Renamed the Rift Blade texture to change its capitalization under
Windows
Removed Redundant Textures

Removed copies of item textures that simply had other names. Some
textures are broken now. I'll fix that in a moment.
Minor Change

Messing with the Rift Blade texture's name again
Fixed Missing Textures and Changed World Thread

Fixed the code for retrieving textures for ItemRiftBlade,
ItemRiftSignature, and ItemRiftRemover. Renamed Rift Blade item texture
again due to capitalization issues. Replaced World Thread texture with a
dark variant of MC's String - we can switch to another texture later.
