fix a bunch of breaks that having a blind file unload has brought

We can't blindly unload here - this loses swallowed content (in swallows,
boxes, tables etc.) ... this here along with an actual implementation of file
unload broke the pager in E for starters as shading then unshading (double
click titlebar) a window would lose the mini preview image obj swallowed in.
also fullscreening would do it. this also broke gadget bar, the xkb gadget in
it too and more... so this is a particularly bad thing break.
