hgweb: show each obsfateentry on its own line

Commits with more than one reason for being obsolete used to just show obsfate
entries all on one line, and that doesn't look good. Let's show each entry on
its own line.

In paper and coal the lines are simply split using a <br> element, and in other
hgweb themes each entry has its own table header. This is done by analogy with
changeset parents and children -- in paper and coal they are all put into one
table row, and everywhere else each one gets a separate row.
