PowerStone Recode

[JaxOf7]

Power Stone code looked messy, also tricky to modify if you wanted a different curve or speed.
So I made it smoother.
Recolored stones included to show what kind of stuff you can do. Red is the one closest to current power stone.

There's actually math here now rather than random numbers being decremented by some arbitrary number.
I'll rename the variables used cause they're kind of ambiguous, but this looks okay otherwise.

Moved to pending.

Edit: Closed.
