hgweb: highlight data of the current revision in annotate view

hgweb: highlight data of the current revision in annotate view

* Distinguish the /annotate/<revision>/<file>#<linenumber> link when it would
  lead to the current page (i.e. <revision> is the current revision) (style it
  gray and undecorated). This indicates more clearly that this is a "dead-end"
  in blame navigation.

* Display lines changed in current revision in green.
