RC : Hide items when not viable

Hides a few of the NavBarAutoHide options when AutoHide
is not enabled.

Also, I went through and restructured our use of getContentResolver.
We were doing that op over and over again.  I just put a protected
global in the parent AOKPfragment and referenced it from there.
