Display welcome screen + tech info

[gelim]

Hi again, I thought you could be interested in a diag_login_screen script that outputs more info in a comprehensive way (if you think parsing of objects for welcome screen is not too flaky you could adapt diag_render_login_screen.py to print out those info as well...

Ouptut looks like this:

    $ python diag_login_screen2.py --host 192.168.32.129

Hey Mathieu! Indeed this is a great idea! Initially thought about the script as a way to help on mass-scanning servers and grabbing info, so this addition is a good one.

Would you mind merging this changes into the original diag_login_screen_info.py? I think at some point your version superseed the old one, so it doesn't make much sense to have both.

[gelim]

Yeah sure. By the way, contacting you via your email in commits is fine for more broad questions?

[martingalloar]

Yes, feel free to reach me there too!

I did another pull request in #14, didn't want to tamper this one with commit about style change etc.

Merged in #14!
