Niels Martin Hansen f1c7ed639d Properly fix "local config" option, previously it only made config.dat local and kept everything else in %APPDATA% still. Now fixed, along with a load of other problematic uses of relative paths. Still a lot more to go.
This also makes a bit of sense of the default options for various paths that previously were implicitly relative to ?user or ?data but never explicitly specified in options.

Originally committed to SVN as r3130.
