hgweb: add link to parents of annotated revision in annotate view
The link is embedded into a div with class="annotate-info" that only shows up
upon hover of the annotate column. To avoid duplicate hover-overs (this new
one and the one coming from link's title), drop "title" attribute from a
element and put it in the annotate-info element.
