gitweb: Identify all summary metadata table rows

In the metadata table of the summary page, all rows have their
id (or class in case of URL) set now. This for example lets sites
easily disable fields they do not want to show in their custom
stylesheet (e.g. they are overly technical or irrelevant for the site).
