Small update to Plugin

[Colin Holgate]

Something seems to be wrong with the new revWebInstallerX86.app. It  
shows up in the Dock, but doesn't have any window. As well as the  
revWebInstaller process there is also one called Updater, and mds gets  
used too. The combined CPU load is over 180%, but nothing ever comes  
of it, eventually you have to force quit revWebInstaller. When you do  
that, Updater starts to take about 90% CPU, so you have to use  
Activity Monitor to force quit that.
