Add contact and version to bottom bar

[GreenLunar]

There is this area on page:

<div class="right body">
                    <a href="/bookie/recent?sort=popular">All Popular Bookmarks</a> |
                    <a href="http://docs.bmark.us">Bookie</a> |
                    <a href="http://github.com/bookieio/Bookie/issues">Support</a> |
                    <a href="https://lib3.net/bookie/dashboard">Dashboard</a> |
                    <a href="https://github.com/bookieio/Bookie/commits/develop">Changes</a> |
                </div>

Add Contact hyperlink (mailto: or http:// link to a contact form page) and Version, similarly to Seeks upper bar. See https://seeks.ru/search?q=bookie

<p id="info-head">
<strong>Seeks version:</strong><span>0.4.1-stable</span>
<strong>Node host:</strong><span>seeks.ru</span>
<!--  -->
<!-- <strong>Options:</strong><span>@websearch-content-analysis@/@websearch-thumbs@/@websearch-clustering@</span> -->
<!--  -->
<strong>Source</strong><span><a href="http://seeks.git.sourceforge.net/git/gitweb.cgi?p=seeks/seeks;a=tree">code</a></span>
<strong></strong><span>Thu Sep 10 00:00:00 MSK 2015</span>
</p>

Doing so, would ease on writing a clear list of Public Bookie Instances.
