PS Update - 14 - Hiding Navbar (Not PIE)

FW: Hiding NavBar - {WIP - DO NOT MERGE}

PS8:
New Structure for Hiding NavBar

ps9 : Fix a few derps.
ps10 : more derps/Try/catch/ etc.
ps11 : Hiding NavBar now Marginall works.
       There are a lot of things that can break this right now.
       it doesn't recover well from toggling itself on/off and
       if you 'hide/show' the NavBar, it doesn't take to that kindly
       either.  One thing the seems have an effect is to change the
       height of the NavBar.  there is something that gets reset in
       PhoneWindowManager by doing the height change that helps.

ps 12 :  Reworked some of the logic.  Added visual hints to indicate where
the swipes should occur.  Also completed landscape (phone) orientation shift
for swipe.  Made several changes in the window layout formulas in
PhoneWindowManager so that NavBar is treated like a real overlay when
in AutoHide Mode.  Otherwise, certain windows and elements were
resizing when the NavBar was shown/hidden.

ps 13:  Add images (button/drag) from NitrozK

ps14:  Start implementation of longpress on handle to launch
       NavRing.  Fix press navbar resets hide timer.

LastApp Toggle [1/2]

Creates an action useable by NavBar & NavRing to toggle
between most recent apps.  Will try to ignore the launcher
when possible.  ie, if you've just rebooted and have not opened any
apps, it will do nothing.  if you open 1 app, it will toggle between
that 1 app and the launcher.  Once two apps have been opened, it will
toggle between those two apps.
It's kind of like opening recents and hitting your #2 slot repeatedly

PS 2:  Add Icons from Hoolm.  {Thanks!}
       Re-wrote the logic for selecting next app.  Rather than
toggling back to launcher if only 1 app open, it does nothing.
toggling only occurs now when there are at least two apps open.
One issue that I still need to work out is that 'Recents' is somehow
showing up as a valid target to toggle to.  It shouldn't.

ps 3:  getRunningTasks() does not filter out 'Excludefromrecents'.
Thus we need checks for 'default launcher' and SystemUI.
as I write this, I realize I might be able to query the
ExcludeFromRecents flag of the package a bit more easily.

ps 4: Whitespace fix.
ps 5: one more whitespace fix.
ps 6: remove unnecessary dependency
