there are atm multiple problems that seem to prevent to have this working.

1. in applet.cpp#132 the line;

QString path = KStandardDirs::locate("appdata","plasmoids/" + 
appletDescription.pluginName() + '/');

KStandardDirs::locate does work on files and not on directories. So, it will 
not find the actual path the *.rb got installed to.

2. the package-handling is imho overdesigned. That are the files in 
workspace/libs/plasma/package* that expect to have a special structure 
of "plasmoids" aka scripts. So, it's not enough any longer to have only a 
*.desktop and a *.rb file to have this working :-/
