remove lindsey specific content

I just want the blog, I don't need any of lindsey's posts, images, or
redirects. the header should also have my stuff in it.

of course, the main page fails to load without any content so there
needs to be some filler. maybe I'll patch that.
switch up the basic styles

let's drop the font and use Arial for now, and use a nice purplish-pink
instead of teal. I also like right-aligned text, and the date looks
better under the title.
move the bio into a partial
use a different date format - %Y.%m.%d
modify styles for the sidebar
changeup the header

I don't want to steal Lindsey's icons, so the nav will just be a bar
with border highlighting that matches the sidebar,
put the archives link in the header
needs moar purple
