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.
