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.
Don't remove the last app
Add option to disable searchbar in recents [2/2]
