[ETF] Entity Texture Features

[V3.1.4]

• fixed a logic mistake causing high lag when additional mob textures (like sheep_fur.png) did not have the same or higher number of variations as the base texture
• the Blocks property now also check the block the mob spawned inside of (allowing things like water, cave_air, flowers, torches, etc. to be used, and also fixes issues with soul-sand and mud not reading correctly)
• added an option to enable / disable block entity emissive and custom textures as they currently do not support vanilla animated textures and may want to be disabled by such users
• added some missed translation support (Still only english atm :/)
