Allow an option to be less verbose

[mandreko]

To make screenshots for pentesting reports, it would be convenient to only show the problematic items. For example, if the TLS Renegotiation, TLS Compression, and Heartbleed detection come back ok, perhaps they could be hidden, to allow the screenshot to not be an entire screen of text.

Obviously, this would not want to be done all the time, so it would be convenient to have an argument that could be passed to allow it.

Sort of related: I found myself checking many sites for HSTS and protocol strength, so I created a script that merges curl and sslscan output into a single line - gives me what I need as a quick (and admittedly incomplete) format to ensure compliance. Thanks for a great tool! My script: https://github.com/CivicActions/devops/blob/master/bin/bod1801.sh
