Blend: the setEasing docs list the easing types and say when a blend made without a spine takes easing

Browse Source 
docs/mcp.md lists the four easingType values. It and the
object.blend.setEasing params text say that a blend made without a
spine takes easingType and ramp once Replace Spine has given it one,
which the set_easing test now checks.
