Update footer info to make Whimsy happier

Whimsy tracks podling web site requirements (among other things).

This should get all the things green--with the exception of the logo
because we do not have one...yet.

               <em>Apache Annotator is an effort undergoing incubation at <a target="_blank" href="https://apache.org/">The Apache Software Foundation (ASF)</a> sponsored by the Apache Incubator PMC. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.</em></p>
