fix console font to be monospaced also for box drawing chars

[m-schmoock]

The c-lightning summary plugin ( https://github.com/lightningd/plugins/tree/master/summary ) prints box drawing unicode characters. Turns out the current UI font is not able to monospace them correctly. See attached screenshot, the bars should be aligned in the middle.

Sounds acceptable to me. Have you tried running it with a monospace font? does it looks good?

@shesek
I tested it only on my nodes CLI and yes there it looks good.
From the screenshot above you can see that the app already uses a fixed font for that activity, BUT the box drawing chars are not fixed for this font. Which some fixed fonts have, as the box chars are UTF8 stuff.

@m-schmoock Any idea which font would be suitable here?

A small research gave me this: https://stackoverflow.com/a/52712484/884474
Try using Lucida Sans Typewriter. If that doesn't work, try to ship it with
https://madmalik.github.io/mononoki or https://github.com/adobe-fonts/source-code-pro . Not sure if embedding a special font in the app is an option. So lets hope Lucida Sans Typewriter does the job ;)
