suggested doc enhancements for xsv 2.4-1

1.  The usage document xsv-status.html should mention that the document arguments on the command line must be URLs not filenames, at least on Windows.  The argument processing code treats a name like c:/testdir/foo.xsd as a URI with scheme c.

2.  The -E and -T options appear twice in the list.

XSV does seem to work nicely, in the brief tests I've tried.
