Shell font

[denouche]

Hello,

Nice project, I really like the embedded shell :)
For the shell to be displayed properly you need to have the font "Inconsolata for Powerline" installed on your computer. Otherwise the cursor will not be placed properly and the shell display width will not be good.
It could be added to the readme to avoid other people spending time to understand why the cursor is misplaced, moreover the font can be found for free here: https://github.com/powerline/fonts/tree/master/Inconsolata
Just tell me if you are ok, I can add it to the readme.

Thanks !

Yes, I know. I'd love the readme to be updated.
What would be even better would be to fix that issue ;-)
