need to change videoIteration according to what is moved around, also add one to index at sortable side

if moving the current iteration, just make iteration equal the new index

if moving video from before iteration to at or after iteration move iteration back 1

if moving video from after iteration to at or before iteration move iteration forward 1

This was derived from the results of movements using the jquery sortable library
