Getting the default file system handle

Hi Andy,

I modified the config as you suggested but xrootd wouldn't start and
started to get 'Unable to load file system wrapper' error. After some
debugging I found that the name of my library was not getting passed
to XrdXrootdloadFileSystem call in XrdXrootdProtocol::Configure
(XrdXrootdConfig.cc line 275). Unless I am missing something again,
there seems to be a typo there that needs to be fixed:

[hartem@log1 XrdXrootd]$ git diff
