commit d3f118be79686adfcd085211ad3a4b3fa892bf4e
Author: Oswald Buddenhagen <o...@users.sf.net>

re-interpret relative local paths in config file
this makes config+data file "sets" relocatable, which is useful for
testing.
this is technically a gratuitous backwards incompatible behavior
change, but to the degree that anyone uses relative paths at all, they
almost certainly rely on PWD being set up such that they won't see a
difference.

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]
The 'isync' compatibility wrapper was removed.
