moved App under App folder... bit strange but looks right place.
removed tons of static member variables. just use $app.
removed unused vars; removed the container also defined in FrontMC.
changed link to cache.php, which does not include anything else.
use raw apc_* functions to cache $app.
use simple functions to boot $app.
bootstrap to construct app and return it.
removed all but loader, which is what $app is for.
