[ETF] Entity Texture Features

[V2.6.RC1] Release Candidate 1

Changes since last Release:

• enabled all versions after 1.18 for snapshot testing

• optimized code with a focus on preventing future mod conflicts

• added "etf/random" directory support thats acts as an override to the "optifine/random" directory as an option for resourcepack devs

• added support for villager profession/type/level textures to use their own properties file (Optifine parity)

• added support for random / custom vanilla glowing eyes (spider, enderman, phantom) (Optifine parity)

• added texture customizing property "teams" to set mob texture by scoreboard team name

• added emissive armour support (Optifine parity)

• added emissive horse armour support (Optifine parity)

• added emissive & random / custom horse marking texture support (Optifine parity)

• added shulker head emissive and random texture support (Optifine parity)

• added a setting to allow illegal characters in texture files like spaces and capitals (Optifine parity)

• added a setting in Custom textures to customize property updating restrictions (E.G if disabled for biomes a desert zombie that walks into a forest will be able to change texture based on the new biome, as opposed to the default behaviour where it will keep its desert skin)

• change: blinking now occurs truly randomly within configured frequency

• change: how optifine properties are applied. (Biome and other non-updating properties will no longer prevent / effect updating properties like health or name.)

• change: mod-menu config option screen tweaks

• change: CIT resewn elytra message removed as CIT now supports ETF emissive elytras

• fix: properties not updating correctly

• fix: property files being read from below resource-packs and applying to textures that should have overridden the custom properties (e.g texture property files will now only apply to textures in the same pack or below packs)

• fix: textures reverting to vanilla after a time with certain property file configurations

• fix: many other simple crashes or unexpected behaviours not worth mentioning
