* optimized model loading system. (less load on RAM)

* added TWO🤯 swords. These are old swords that have been in the resource pack for a long time. Now if you move the sword in the off hand, it is not just moved behind the back or left on the belt. The sword is stowed in the scabbard, which makes the sword more detailed and elaborate.

* Each scabbard is unique.

* All future swords will be made in a similar style.
