added animation to movement

The movement now has animation and a particle effect.  Not exactly how I imagined it but it does the job.

Had one minor issue with the anim that I needed to fix.  I turns out if a trigger is set in a state that can't "use" it the trigger stays set until you move to a state that can.   That was causing my anim to play twice because the movement was so fast.   The solution I used was to duplicate my anim state and let them transition to each other with the trigger.  Now the anims will interrupt each other if you click really fast and will never play twice.
