Create a class for definning a filter for searchForEntries() #530

The filtering parameter in searchForEntries() is a plain list, which contain several levels. It would be better to create a BiodbFilter class with different subclasses (BiodbFilterAnd, BiodbFilterOr, BiodbFilterText, BiodbFilterNumRange, etc) that could be combined. Maybe using plain functions to simplify instantiation: mkTxtFilter(), mkNumFilter(), mkOrFilter(), etc.
