Features in KDE Base
-extend kross::plugin to be multiinstantiable even more.
-add a 'searchingpath' feature to kross::action.
this way we can use relative urls in scripts.rc scripts will be looked in system, home, or custom-specified (when using new c'tor) location. i needed this as Lokalize allows projects to be relocatable and be shared among several people
-implement scripts.rc saving in plugin d'tor (only if file already existed).
this is the first step in implementing GUI-based scripts.rc editing.
-optimize the model a bit.
