Website to include current-event banner

[Roy Lenferink]

Hi all,

I came to the Apache Avro project to update the website to add a banner for
the latest apache events.
This is as a follow up for the e-mail Rich Bowen sent [1]

I think the best position to place such a banner is in the div with id
"credit2". It looks good to me to update the <div id="credit2"></div> to
include the following piece of html:
<a href="https://www.apache.org/events/current-event.html";><img src="
https://www.apache.org/events/current-event-125x125.png";
style="padding-top:0.5em; "></a>

Another thing I noticed while having a look at the website for Apache Avro.
The footer containers the following copyright statement:
Apache Hadoop, Hadoop, Apache, the Apache feather logo, and the Apache
Hadoop project logo are either registered trademarks or trademarks of the
Apache Software Foundation in the United States and other countries.

It is probably better to have this changed to:
Apache Avro, Avro, Apache, the Apache feather logo, and the Apache Avro
project logo are either registered trademarks or trademarks of the Apache
Software Foundation in the United States and other countries.

As these changes are so small, it is probably easier if a committer applied
the changes directly instead of providing a patch with changes. If not,
please let me know how I can provide this change ;)

Cheers,
Roy
