LPFaint99 e4fa493a27 Adds the option to change the path to the wii nand root
when nand root is changed the current sysconf is saved,
and the sysconf in the new location is either loaded (if exists)
or the default sysconf is created
wii menu item is updated when the root changes
small fix to saving gamelist paths to .ini paths that are removed from the gui are now removed from the ini instead of simply changing the number of paths
