Added some encoding to the 'link' value returned by 'readlink' so that links are not interpreted as relative.
Created section of 'getNode' that can mimic a VOSpace node when given an 'http' based uri.  This enables links to 'http' resource in VOSpace to be handled by the FS layer.  This involved creating a 'link' check in the fixURI method of Client and an 'http' branch 'getNode'.
Merge branch 'master' into fs_links
the extra bit of logic was not useful here.  removed.
Merge pull request #39 from canfar/fs_links
