Add 'Blink' feature in Ember Table

问题

Here are issues

• if click on an updating column (to sort) blink feature does not work.

• if i try to filter, blink feature goes crazy.

i am not sure if there are better ways to implement 'Blink'. Because i'm not sure the way i keep 'previousValue' and apply'clearStyles' method are correct.

here is the link to previous discussion. How to apply 'Blink' feature in Ember Table? Kindly add suggestions.
