Script Summary: Hides the Zs: 0 in the Zombja Sonar
This removes the extraneous "Zs: 0" entries in the Zombja Sonar map, making it much much easier to find the last few remaining Zs and summon the Zombulator.
This script has only been tested on Firefox 3.6.3, however it is a very basic script and I can not think of any reason why it would not work on any browser that supports Userscripts.
