summary: use shared changelog_table implementation on summary page

The main purpose of this change is to simplify code and avoid duplication.

Using the shared implementation also happens to give a slightly different view
of the changesets. There will be no table headers, the columns are shown in
different order, author gravatars are shown, commit messages can be expanded,
and there is slightly different styling.

Small remaining amounts of template code is moved from
changelog_summary_data.html to summary.html.

Patch modified by Mads Kiilerich.
