Fix a minor copy/paste omission.
Update to loggability 0.4 and add Rubinius (1.9-mode) fixes.
Added a test for propagating config defaults.
Set indent for specs, too
Make missing config values return nil instead of auto-vivifying to a Struct.

was done to detect non-existant values than was saved by the debatable
convenience of being able to auto-create nested structs.
