The design has been slightly modernized in the process.
jQuery was also removed as it is no longer required, resulting in
faster page loading times.
Gallery thumbnails were regenerated at an higher resolution to match
the new design.
[FastClick](https://github.com/ftlabs/fastclick) is no longer relevant as all modern mobile browsers suppress the touch delay when a responsive meta `viewport` tag is present.
Commit 8933085fce11667a8f734987b45193a65a8bbff3 deleted main.js,
but mistakenly removed the link to main.css instead of main.js.
The link to main.css was re-added in d675df7220404a806d029146478d321b7af3e137.
