Add build timstamp to the bottom on MUDROD WebUI

[lewismc]

If you scroll the bottom of the application hosted at Any23.org you will see a very smart Apache Any23 v.2.1-SNAPSHOT (2017-06-05 19:11:41+0000) application and timestamp signature which indicates very clearly what functionality should be present and expected from the application.
The code to implement that can be found at the following
https://github.com/apache/any23/blob/master/service/src/main/resources/form.html#L323
It is very simple and we should consider implementing something similar.
