rockbox/apps/gui/statusbar-skinned.c
Jonathan Gordon 9928e3418f Another major skin backend update/hopefully bugfix:
Skins are now more self contained in the skin manager which in the future might allow on demand skin loading (i.e smaller skin buffers)
Skin backdrops are also managed more intelegently (fixes a bug where you can get a crazy backdrop loaded if a .sbs fails to load)

the rockbox_default rescue theme is now called rockbox_failsafe to better express what it actually is.

This commit hopefully/maybe fixes the heavily reported data aborts, so please check if you are getting them
