hgweb: use webutil.branchentries for branches on summary page

hgweb: use webutil.branchentries for branches on summary page

This allows showing correct status for each branch, which was missing on
/summary. Usually that means that closed branches get the same css class
(resulting in e.g. different color/shade) as they do on /branches page.

The sorting of the branches on summary page also changes and is now the same as
on /branches page: closed branches are now at the end of the list.
