Bacon fonts

- Headlines
- Replaced medium headline webfont with regular
- Font sizes tweaks
- Temporarily made social icons look fine (should still be replaced)
- Logo svg is optimised
- Byline is bold

Personally I think this is releasable, for now it should go into the bacon branch but I'm pretty confident it can go into master (will have a chat with Chris about it).
