World Game Update v0.0.1.5

Another update to World Game! It took me so long to update the game because I went traveling for 2 weeks and couldn't work on the game. When I returned last week, I started working on the update. Anyway here's the Changelog:

• Added ability to save or load worlds. (currently only saves/loads blocks, doesn't save items and entities)
• Added NPC Loot drops on death.
• Slight Perlin noise optimization.
• Increased crosshair size and replaced its texture.
• Loot tables are now serialized JSON files inside the "Game Files/" folder.
• Fixed mining animation persisting when opening inventory while mining a block.
• Fixed mining animation sometimes doesn't immediately play when trying to mine blocks.
• [back-end] Loot Tables will now be loaded into the registry instead of being stored within every block.
• [back-end] The Loot Table class is now a struct.

[back-end] = Features not added to the game, but is inside the game's code.

If you find any bugs, please report them. Have Fun! :)
