[ETF] Entity Texture Features

[6.2.6]

• update to minecraft 1.21.2+
• added the minecraftVersion property to vary textures based on the current minecraft version, supports ranges e.g. 1.17-1.18.2
• due to armor texture location changes emissive trims can now be found at
  • textures/trims/entity/humanoid/<trim_type>_<material>_e.png
  • textures/trims/entity/humanoid_leggings/<trim_type>_<material>_e.png
  • e.g. textures/trims/entity/humanoid_leggings/rib_redstone_e.png
  • this may yet be reverted if OptiFine opts to keep the old directory

• fixed a logical error that would make spawn locked properties occasionally override the fact that non spawn locked properties were still present and still needed future updates.
• fixed block entities not updating when using non spawn locked properties.
• made the properties settings screen list display in alphabetical order.
• removed log spam if ETF accidentally read a cit .properties file, due to a texture pointing there.
• ensured all ETF logs pre append [ETF]: for easier log filtering.
• added the blockBelow && blockBelowSolid properties to vary textures based on the first non-air block below the entity, no matter the distance, the latter only triggers for the first solid block found.
• added the blockAbove && blockAboveSolid properties to vary textures based on the first non-air block above the entity, no matter the distance, the latter only triggers for the first solid block found.
