Subject: [PATCH] Output code to explicitly reference favicons.

This makes favicons work when Laconica is not installed at a web
server's DOCUMENT_ROOT. I've also added the capability to override the
Laconica default favicon.ico file with a theme-specific one simply by
dropping a themed favicon.ico in the appropriate theme directory.
