Improved KnightOS redesign

Hi KnightOS team,

After releasing the new design on /g/, a couple of Anons pointed out some weaknesses in the design. I have tried to redesign the site in accordance to the new design, while fixing some problems, for example, mobile views.

At first I thought that Github was able to handle multiple Jekyll sites, but it appears that the [GIthub link](http://altbdoor.github.io/knightos.org/) is broken. However, it appears fine on local testing.

Regards.
