Viewing failed attempts

Hey quickbreach,

Loved the Defcon presentation. I have been testing out the tool on an engagement. In my use I found it might be useful to be able to view/output failed relay attempts. I did see I could log success attempts, but thought failed may be a useful switch as well. I took a quick peek, but I am far to much of a novice coder to be able to edit that on my own. Let me know what you think.

Thanks
