Subject: Handle missing optional site files gracefully

Two site files the theme reads were assumed to exist. A site without
templates/logo.txt got an empty preformatted block at the top of every
page in both output formats, styled with the logo's margins, rather than
no logo at all. A typo in params.custom_css produced a nil pointer
error naming only the template line, since the result of resources.Get
was used without checking it.

Skip the header entirely when there is no logo, and report a missing
stylesheet by name.
