Fix up 'clear recents' UX.

Use the 'dismiss all' button drawable and place the button in the upper
right corner. Doing so fixes the broken animation when going into
recents.

Clear Recent Apps (From NavBar)

Original author: TheMrcool212

this is not using cm's clear recents way, cm uses a button to clear recents but mrcool coded like pa's way at kk based pa roms so navbar recents button turns to clear all button when you open recents menu.
