Highlight request failed message

fixes #89 
I feel there should be an indication through the page also, because, i think that, new users would be more susceptible to miss out on the terminal output, as they'd be more focused on the frontend side. 
I highlighted the request failed message, so that it captures attention, doesnt completely solve our issue, but should be good. I have a really neat idea on improving duckpan, give me some time, ill handle this as well.
