Fixes:

Fixed an issue where custom skulls using player names or textures from minecraft-heads.com weren't working
- https://textures.minecraft.net/texture/ is no longer needed in the player field
- You can simply put 1ee3126ff2c343da525eef2b93272b9fed36273d0ea08c2616b80009948ad57e and it should work.

Changes:

Starting to remove reliance on NBT-API, It should not impact current configurations.
