[ETF] Entity Texture Features - [Fabric & Forge]

[4.5.1]
- fixed painting variants only working in the vanilla directory and not the optifine/etf folders
- reverted some changes to `pattern` string comparisons as the OptiFine doc was incorrect compared to actual OptiFine behaviour
- fixed a crash related to `pattern` string comparison handling changes in 4.5.0

[4.5]
- added more code to support EMF
- added a new logo
- added support for random & emissive painting textures
- added support for emissive armor trims the same format as OptiFine *(note this seems to break if iris and 3d skin layers are both installed, no idea why, it also fixes itself if a mob in the background is wearing the same trim, I'm tired of pulling my hair out about this so this is just how it will be for now)*
- added support for armor trim overrides *(e.g. the texture "textures\trims\models\armor\coast_redstone.png" will override the autogenerated trim if present)*
- added support for end crystal random and emissive textures
- added an option to enable extra warden textures like the heart to apply to the entire model
- textures ending with numbers now use the separator "." like OptiFine for variants *(e.g "mob4.png" now variates with "mob4.2.png")*
- Animatica textures are now detected and prevent certain ETF actions that could break these textures *(MoreMcmeta was already supported)*
- added new ETF skin feature to allow/prevent transparency for your skin specifically, plus general improvements to skin transparency handling.
- added new ETF skin feature variant of the villager nose setting that can use a custom texture set in the skin, instead of the default villager.

- updated the `minecraftcapes.net` api url when used in skin features
- improved the handling of "_eyes" textures
- tweaked the skin tool failure dialogue to be more informative and helpful
- tweaked warning messages and added some
- tweaked the resource-pack screen etf button

- fixed `biome` property breaking when using "CamelCase" instead of "snake_case"
- fixed `size` property being off by 1 when compared to OptiFine
- fixed `name` property not working for players usernames
- fixed custom ETF cape textures not working with `physics mod` capes
- fixed `3D skin layers mod` emissive body pixels with skin features
- tweaked some `en_us` translations
- fixed 2 forge crashes
- fixed `pattern` & `ipattern` to correctly match the OptiFine behaviour
