Modernization.
More modernization.

Arrays suck.
Added overloads of save() that let you save to binary.

Also use Closer.
Modernize this save-out as well.
Just nix ManagedConfig.NAME_ORDERING.

Pretty much the only thing that cares about this is the config tools
so just inline it in there. I guess I'm souring on having random
public static final singleton utility dinguses when you can just
create them as-needed... I suppose I could expose it as a static
class under ManagedConfig for people who want it, but meh.
Added a saveAll() overload with many options.
Use ConfigManager's new saveAll() overload.

- We can save to any directory, not just under rsrc.
- XML/Binary and extension control.
