A popup window to tell users what new features are up
when there is a new release. This is debatable between
annoying and nice: people hate popups, but people
won't know about most of the cool new changes as things
slowly progress. some possible asweres:
* it displays once for a user every release
* it displays each time they access the u9k and has a
"don't show this popup again" which applies until the
next release
* it displays each time they access the u9k and has a
"Never show news popup" checkbox which is forever
* both of the latter
