[ETF] Entity Texture Features

fixed Image is not allocated. crash related to armor rendering
added a printout to the right click debug to tell users where the .properties and variant files can go, useful for modded entities.
slightly tweaked sleeping detection for blinking
fixed a crash related to unexpected null values #234
fixed _eye textures not variating correctly since v5.0
fixed the nose button getting stuck in a loop in the skin settings
fixed a crash when removing skin features in the skin tool
added an emissive setting to disable Armor & Trims as it has been known to have issues with modded armors and requires future reworking

[5.2] with the new optimizations in how properties work now I don't need to worry too much about adding too many of them, that being said, I've added a bunch of new properties mostly introducing some external non-entity values. Such as irl time & date, and language based localization. Allowing seasonal entity variation, or language variations for any text in your textures.

fixed player emissives breaking with bright render mode
tweaked mob spawner code
added the isSpawner property which is true if the entity is a miniature mob inside a spawner block
the color property now also reads modded entity colors if the entity extends VariantHolder<T> with T being either DyeColor or an Optional<DyeColor>
the profession property should work for all modded mobs implementing VillagerDataContainer
added the following irl time & date properties hour,minute,second,month,year,monthDay,weekDay,yearDay. they are all numeric integers and support ranges e.g. "0 2 4-7". hour,minute,second will update over time, the others will only be set when the entity spawns. hour is in 24-hour format, 0 - 23. weekDay starts with sunday which is 1 up to saturday at 7. month starts with january which is 0 up to december at 11. yearDay is 1 - 366. monthDay is 1 - 31. april fools is thus month=3, monthDay=1,The Christmas to new-years period is month=11, monthDay=25-31
added the dimension property, which takes in a list of strings, or regex: or pattern:, and will be true if matching the entities current dimension. Vanilla dimensions are overworld, the_nether, the_end. Modded dimension names are entirely up to whatever the mod maker set them to be, expect mod_name:dimension_name. If you start the property text with print: it will work as normal but will also print the found dimension, to help with discovering modded dimension names.
added the language property, which takes in a list of strings, or regex: or pattern:, and will match to the users chosen in-game language to facilitate the localization of textures if desired. default is en_us and corresponds to the ??_?? format language code of the games language files. Helpful if your texture or model includes text for some reason.
added the light property, which takes a list of integers and support ranges e.g. "0 2 4-7", and matches it to the light level of the block the entity is standing on 0 - 15, -1 will be returned if there is some error. This property updates over time. An example use could be differentiating aggressive or passive spiders.
