patch for improved CLI usage message

[dingo35]

Hi all,

Always when I am going to play with vompclient I keep forgetting which command line parameters I need to get the logging on screen. The "usage" message when doing vompclient -h does not help me, so here is a patch to improve the help message:

Perhaps someone (Marten?) can improve on the -c and -s message, I really can't figure out what this is doing!

Marten, could you put this into git? Thanks!
