Add more field in the skin file database
Update some block models
Fix skin file database config issue
Remove skin wardrobe database support
Refactor skin animation play context
NOTE: We removed the skin wardrobe database, the multiple servers always synchronize player data by other mods/plugins, so the skin wardrobe database design dispensable. because we can't synchronize all player data, but only synchronize skin wardrobe data part it will conflict other synchronization mods/plugins.
