re-interpret relative local paths in config file

Changed default config & state locations to follow the XDG basedir spec.
|
||||
The old locations remain supported.
|
||||
|
||||
The reference point for relative local paths in the configuration file
|

is now the file's containing directory.

[1.4.0]
