Update web address in startup banner
The startup banner still shows the legacy address for the project home page, http://hallaweb.jlab.org/podd. This should be updated to https://redmine.jlab.org/projects/podd or maybe something else, say https://podd.jlab.org. (CLARA has its own subdomain, for example—why shouldn't we think big, too?) Alternatively we could set up a page on github.io.
