Make /info a bit more user friendly

[mdosch]

If you use /info contact while you're in a chat window with "contact" profanity doesn't show the info but only tells you that it's not necessary to specify the contact.

Expected Behavior

Show you the info anyway but additionally inform that it's not necessary to specify the contact.

Current Behavior

Profanity doesn't show the info but only tells you that it's not necessary to specify the contact.

Steps to Reproduce (for bugs)

1. /msg contact
2. /info contact
3. Profanity shows only No parameter required when in chat
4. /info
5. The info is shown

The behavior for /status is the same.

I'm not sure what's the best expected behaviour.
It could be that the user types /info someotheruser which is not the one he has in the active chat window.
So I think the correct behaviour would be: use the second parameter always if specified. If not use the nick of the active window when in a chat. And never notify about additional parameter. The only thing is that the output will then only be in console window.

I guess that would be a good solution.
