This uses svg <use href="#..."> to avoid having to duplicate the
logo at every use. Surprisingly this just works with the current
theme css, and doesn't require any changes.
Makes the styles of search results work better with narrower
screens. The category badges on each result collapse to just an
icon (with title text) when the screen is too narrow.
Adds a text label for the Forge/Fabric icons.
Adds a message for when a query returns no results.
