Subject: Config: fix OsPath values

my annoyance with conferer increases. It should really, /really/ be a
compile error if a thing used in the config does not have a FromConfig
instance. Or at least the documentation should mention that in such
cases it will simply always take the default value without telling
anyone, instead of just saying "the generic instance has reasonable
defaults" (well, /which/ defaults?)
