Check families and levels before set

* Implement New Revit Family option

* Filter family types for 'Family Instance'

* Adjust available mapping methods according to selection

* Set hard coded categories just once and source families when source set/updated

* Implement family instance mapping

* Pass group selection info if only group selected

* Exclude definitions from conversion escape

- Previously we were using definition mappings only for direct shape conversions but now they can live in instances

* Add direct shape option to components back

* Calculate rotation of family instance

* Fix transformation matrix

* Use insertion point for instances

* Set inputs for mapped definition
