[PATCH] svnversion should its help messages to stdout

Hi,

This patch changes output destination of help messages for 'svnversion'
and 'svnversion --help'.

Since users often read help messages with a pager such as 'more' or 'less',
commands should output its help message not to stderr but to stdout.
It seems that svn, svnadmin, svnlook, svnserve, and svndumpfilter do so,
but svnversion does not.

Thanks,
