Simple Skins [Redo]

Note : This is a fork of simple_skins mod created by TenPlus1, it offers several improvements over the old mod and comes with 800+ predownloaded skins. Preview feature requires clients 5.4+. Works fine with both multicraft and minetest. Completely tested on sfinv, unified_inventory

Simple Skins mod for Minetest uses SFInv, Inventory Plus or Unified Inventory mods when available to allow players to select a skin/texture from the list.

Further Improvements

• When preview is disabled shift list formspec to side of screen and change camera to front third person view as to see the changes being applied. "Nicos servers have it but did not made the code public."
• Add a downloader script
• Improve the convertor script to allow converting even minecraft skins
• Fix some issues in meta fixer script. ( need to removed or merged into downloader script)
