This is the first step of making the resource browser, related to blueprint swift-ui-improvements. Adds three attrs to DataTableOptions: .. attribute:: mixed_data_type .. attribute:: data_types .. attribute:: data_type_name Adds attr to Column class: .. attribute:: allowed_data_types Adds attr to Action and LinkAction class: .. attribute:: allowed_data_types Changes implentation of FilterAction. Adds MixedDataTableView. Change-Id: I45fce5e889e92abc592f0a5abfef1abb4ce527be
