Centering Logo with Alpha 6 Navbar

Created by: ghost

I'm not overly familiar with Flexbox but i've updated to Alpha 6 and of course due to the new changes, my navbar broke.

I used to use mx-auto on my nav logo and then set a width to center it on the navbar but i can't seem to find a way to do this now with A6.

I can get it to 'partially' center in that its offset by a few pixels but as soon as i add another link on either side, it moves.

Any suggestions how to do this? Or would it be possible to push a PR to add a class to do this?

Cheers
