Modernize bankKiller, OdinTypesFilter, OdinBCIDFilter

Use Gaudi::Property, and use the opportunity to replace string options by dedicated types -- this results in additional validity checking of properties, i.e. mis-spelled items are are recognized as such by the parser, and result in an error. It also should improve CPU efficiency, as all strings are converted to integers or (strongly typed) enums during the parsing, and hence during event processing no strings are created and compared, but instead only ints are compared.
