hgweb: move common vertex code to Graph.prototype
Just to give some context to the return values: vertex() needs to return two
HTML elements as strings, <li> to be used as a background and a <li> to be
shown in foreground. The latter was made obsolete recently when changesets
started to be rendered server-side, but background elements are still useful
for now.
