bunny up ears

so i decided to tackle the most difficult part of this particular morph.  the ears.

on the left is my version for personal use. as you can see it does not blend seemlessly with the head because i just use it as a shape and color proxy, even erasing it completly if need be.  the right is by doing the same process but as seen it does not work when you move the hear.  my guess to fix it is to make the ears fit the base mesh first then use corrective morphs for the various other morph sets
