Hidden layers took a removed layer out of the default configuration's
top-level ON, OFF, Order and Locked lists only. A sub-list of /Order, a
radio-button group (/RBGroups), a usage rule (/AS) and every alternate
configuration in /Configs still named it, so its dictionary, name
included, stayed in the full-rewrite save.
The removal now cleans all of these lists, through nested arrays, in the
default configuration and in every alternate one. A usage rule left with
no layer goes.
