Major changes in 0.0.2:
* Updated to work win gio-standalone 0.1.2
* Build fixes on various platforms
* Don't link client lib to libgvfscommon.so
* Change how the uri mapper works
* Integrate standard uri mappers (i.e. smb) into client libs
  (You might need to remove $prefix/lib/gvfs/modules/libsmb.so
   from an older version if you install this)
* Cleanly handle when gvfs daemons die, without
  crashing the app
* Implement unmounting
* Rename master daemon to "gvfsd" and mount daemons to
  names like "gvfsd-sftp".
