Fixed "Create Random Effects"so it doesnt create None.None on failure to get an effect.
Before it would try once to get and random effect and compare against the list of effects not to use. Now it tries 10 times.

Fixed, Ripple (Case caused it not to render)/. This is like the third time of putting this fix back in.
