path: refactor
Somewhat less ifdeffery, higher flexibility. Now there are 3 separate config file resolvers for 3 platforms (unix, win, osx), and they can still interact with each other somewhat. For example, OSX for now uses most of Unix, but adds the OSX bundle path. This can be extended to resolve very specific platform paths, such as location of the desktop. Most of the Unix specific code moves to path-unix.c. The behavior should be the same - if not, it is likely a bug.
