ui: added smart search box

This change switches the search box in the search view from QLineEdit to the derived QtSmartSearchBox implementation,
which is capeable of displaying tokens of the query as selectable button elements in different colors. It allows for all
the usual mouse and keyboard interactions that the QLineEdit offers.
