Fix bug #776:
  Let the dumper call svn_fs_contents_changed() on any two nodes.

* libsvn_fs/tree.c (svn_fs_contents_changed): remove the artifical
  restriction requiring that we compare two files.
  svn_fs__things_different() certainly doesn't care; it's just
  comparing data-keys and prop-keys.  Heck, we could compare a file
  against a dir if we wanted!
