Edited CSS so that popup link doesn't "disappear".

Popup links were turning white after users clicked on the link.  This
was due to the fact that a:visited included color:#fff;  <-- necessary
to keep the links in the header from turning blue.  Two lines in
npstheme.css were corrected to point specifically to #parkShortName and
.orgLogo's a:visited.
