Review request for kdelibs and David Faure.


Summary
-------

In commit 1128695 I ported kregexpeditor to K_PLUGIN_FACTORY.
This patch change the code in KFindDialog so that it can load kregexpeditor dialog again.
I don't know if it's the good way to do it, but KServiceTypeTrader::createInstanceFromQuery()
returns with the error "No service matching the requirements was found"
