Title: [Proposal] Accept array of string wrapped integers as input for ->sync()

When you're using the an array from a form (with a bunch of "input[]" style inputs) the cells of the resulting array is formatted as strings. Instead of having to make make it into an array of integers to use with ->sync() it would be convenient if laravel took care of that for you.
