huge refactoring of content and theme

- de-personalize the theme as much as possible, moving personal info into config.toml parameters
- extract hard-coded content out layouts and into actual /content (especially home page and all of its assets)
- include full text of posts in RSS feed (aka making the world a better place)
- use abstract layout for both video pages (/leo and /birthday)
