Re-themed it

Eventual TODOs:
-   Some kind of portable theme gadget would be pretty cool.
-   It would be nice to create a vanilla theme, and create a separate
    repo to house my blog.
-   Take a look at the setup code. I'm sure it doesn't set up everything
    correctly, and I don't even know if my dependencies are right.
-   There should be a way to manage pages.
-   Syntax highlighting!

I'll detail these more when I file issues for them on github.
