Imported Adam Kidders search configuration widgets from playground/base/nepomuk/search_widgets_test. I adjusted some names of classes and members and also changed some parts of the implementation, but conceptually the concept is 1:1 like provided by Adam in playground.

Currently the UI works quite well, but the creating of the query string has not been integrated yet.
