Editing Custom files (section)

==Overview==
This new mechanism simplifies sharing custom textures and models with other players. The old method of implementing these files was to apply an AFP patch to <code>ItemTextureEP4.afs</code> or <code>ItemModelEP4.afs</code> using AFS Manager or another tool to open and modify AFS files.

The motivation for these changes was to provide fixes for some vanilla textures that have cache collisions. A cache collision occurs when the "PSO ID" in the texture .dds or .xvr matches another texture. PSO BB considers these as the same texture and will use only the first one loaded. 

Another motivation is to allow providing new files to extend existing functionality. For example, more photon bullet colors.
