Better visibility of recharging power

[flashbackflip]

Well, it all is said in the title - if the visibility of recharging powers would be better, we could plan attacks more precise..

Now i can track some powers that recharge fast but fail to do this with those with the long cycle

Just make depleted power more whitish and the fill-up image more colorful.. I hope it's not too complicated and it would help A LOT

thank u devs!

UPD: or even a timer could b implemented
