Improved HL: Alyx Barnacle

Improves CrazCrypto's port of the Half-Life: Alyx barnacle a bit and adds new things. I made this as a personal thing but might as well publish it for everyone to use. MMOD & HL2: Update Version Improvements and additions: Fixed some clipping issues with some animations Redid the textures and materials, now it looks a bit darker and more saturated, also decals Changed the human eating animations to look a bit better and changed the speed of most animations Added 6 new idle animations for a bit of variety New more accurate sounds as well as more instances of them being used (for example, it now grunts when shot at instead of just making no noise) Added blood particles when it bites a victim (due to limitations it might use the wrong blood for certain npcs but it should be the right one on most) * Added Black Mesa's "stink" particles Enjoy!
