src: removed query syntax

This change removes the query syntax from the QtSmartSearchbox and all its classes. Now it only autocompletes to one
single Token, but the UI functionality for composing a query of multiple elements is still left for later use. The struct
SearchMatch is now used in the whole pipeline for passing search results back and forth.
