General updates to model render (Patreon)

I completely remade the tail to be more cat tail like :3 and it also has the ability to be fluffy and stuff~ It can be very bendy too.

I also made it so the main body can also be fluffy but theres a weird wrinkling effect going on so Ill be fixing this later on~

And I also added just some small extra facial stuff but just very little.

Also made the paw pads more round and u can just about see them at the bottom :P
