Skin Manager v2.4
Added async texture loading from @mspielberg
(PR #6 , #7 )
Uses a native C DLL to load images, generate mipmaps, and compress the textures to DXT1/5 format.
Caches the compressed textures to a new "Cache" subdirectory.
The StbImage.dll has to be included in the mod directory next to SkinManagerMod.dll.
