Show an update notice after the profile is updated [fixes #102]
More idiomatic hiccup.
Fix escaped entities in /project nav.
Highlight org.clojars.* forks [issue #77]

This highlights org.clojars.* forks with italics anywhere jar-link is used,
which includes:

* the search results page
* the dashboard
* the projects browse page
* the header on the jar view page
* the header on the versions page (another change in this commit)
* probably other places I'm not aware of

It also adds a notice to the view page for a jar if it is a fork,
and a notice to the top of the search results if any forks are in
the result set. The notice links to the Groups wiki page for more
information.
When indexing, leave the newest non-snapshot in the index.

Fixes #121.
