New color theme for the site.
I was starting to get tired of the old violet-blue colors of old so I've decided to change the visual theme to a dark orange one which should be easy on the eye.
I've re-rendered some images from their 3D models with the new palette, and took the opportunity to make the home page layout a bit more compatible with small screens found on phones / tablets. I hope I haven't missed anything blue in a deep recess of the site, if you see anything which looks funny don't hesitate to mention it to me.
