Remove breadcrumb
Fix footer links

They were jumping sizes and not quite aligned correctly at the
$larger-width breakpoint
Make sure full menu width can take any width value

Works best if the specified size is at least 45em (noted in _nav.scss)
Update search style details

Fix pagination and a few other details
Use small header logo for narrow widths
Use full font stack after small caps fonts in .small-caps class

Allows for fallback characters for stuff that's not specified in the
font
