Titlebar Modification

[sennafaris28]

First and foremost, thank you for realizing the concept from r/unixporn!

When I tried to use your config, I was having difficulties on implementing window title and window icon. Usually I just add awful.widget.iconwidget(c) to the titlebar setup, but because yours is kinda different then what other config I have tried and the docs, I ended up with broken titlebar with no buttons nor icon. Could you shed this lua noob some light please on how to implement window title and window icon on your amazing config ?
