hgweb: plug followlines action in annotate view

Add the followlines.js script and corresponding parameters as data attribute
on <tbody class="sourcelines"> element.
Extend CSS rules so that they also match the DOM structure of annotate view.

As previously, only address paper and gitweb styles (other styles do not have
followlines at all).
