Site redesign

[CounterPillow]

Bootstrap 2's look is mildly dated, it might be good to do something else.

• Probably don't have blog posts in wells, use panels or something
• Redesign front page to have the important links easily visible, and explain what Overviewer is in one or two short paragraphs and a screenshot

Maybe use Bootstrap 4? Maybe use something else entirely? Who knows!
