[Feature Request] v-select event that returns selected/deselected items when using the multiple prop

[jonabox]

Problem to solve

Currently I have to store a copy of my v-model to be able to determine what items I added or removed to or from the array selection, like so:

<v-select
multiple
v-model="selection"
:items="options"
@input="(selection) => findDifference(selection, previousSelection)"
></v-select>

I then have to find the difference of selection and previousSelection to figure out which item was just added or removed. Finally I have to add some more logic to figure whether the item was added or removed. It would be usefull for me if the @input event also told me which item I just added or removed into/out of my v-model array. Currently, it only gives me the full selection array.

Proposed solution

two additional parameters (added, removed) with @input that store the added or removed element like so:

<v-select
multiple
v-model="selection"
:items="options"
@input="(selection, added, removed) => validate(selection, added, removed)"
></v-select>

Just hit this today 😄 Would be great to have this supported in V3; ideally the change event would supply the item.
