Forcing jar reload on new version

[Daniel Nilsson]

Could you consider including the version number in the filename of the applet's jar-file. I'm asking this because the java plug-in caches the jar so I never get the updates. Changing the filename will force a reload every time there is a new version of Rubicon.
Closing and restarting the browser will get me the latest version but I very seldom close it because I often keep some tabs open for days. If there is another way to force a reload that would be OK too.
