Use JavaScript font loading.

On slow mobile connections web fonts loading is blocking text rendering;
it leaves the web page empty although all images and colors are laid
out. When fonts are loaded via JavaScript, text content will be rendered
with system fonts immediately and updated when web fonts are finished
loading.

Refactor base layout and move JavaScript code to separate template
blocks.
