[PATCH 1/2] config: add root-desc-html and repo.desc-html

[Andy Green]

These are optional, default-empty raw html strings that
are emitted after the corresponding text-only versions
root-desc and repo.desc when they are used in the header
area.

This provides a flexible way to place buttons or links
in the header region for both the repo index page and
for repos individually.

The existing root-desc and repo.desc keep their original
meaning as a shortish text-only repo description.
