Having EDU in the same window as Taskbar causes it to be above All Apps and other system views such as the notification tray. This change refactors the existing All Apps window to accomodate more AFVs so that EDU can also exist in it. Demo: http://shortn/_Qcki3gwvf7 Test: Manual Fix: 232177330 Change-Id: I1bef31d798041a90a0c3e033e71be63898fa5fbc
