Knowledge base widget

This is a plasmoid using the Opendesktop dataengine shipped with KDE 4.3

it shows the last items inserted in the Opendesktop knowledge base,
supporting search among the old entries.
It's a C++ based plasmoid, best tested with KDE 4.4 trunk but should work fine
with 4.3 too.

It will be part of the default distribution of KDE 4.4.


I wrote that also to test the knowledge base part of the dataengine and the library that i was writing (will be easy to do totally different applets using the same engine), but for that big thanks go to the original authors of the opendesktop library :)
