hgweb: parameterize the tag name of elements holding followlines selection
While plugging followlines.js into "annotate" view, we'll need to walk a
different DOM structure from that of "filerevision" view. In particular, the
selectable source line element is a <tr> in annotate view (in contrast with a
<span> in filerevision view). So make this tag name a parameter of
followlines.js script by passing its value as a "selectabletag" data attribute
of <pre class="sourcelines"> element.
As <pre class="sourcelines"> tags are getting quite long in templates, rewrite
them on several lines.
