Jellyfish update and random waves in VOPs

Switched back to using the points on the head's mesh as the template points for the copy SOP. However, this time I used the points on the edge of the head instead, adjusting the width of the tentacles so they would appear to be branching out from the head. The tentacles also have more rotating motion now due to the head's huge expanding and contracting motion. It looks slightly weird now, but it'll be better once it goes through CHOPs. Another change is the removal the multiplication of the noise with the custom attribute sortY that was created. The reason for this was that it made the tentacles transform differently from the head, causing the tentacles to become detached from the head.

Just some waves I created in VOPs with the sine function, the random function and noise.
