Project identity and Teamwork

Solo and unsaved projects: the first sync writes a random key into the project as an add-on object named Archicad2Blender.ProjectKey, as one undoable step. It survives renames, moves and the first save of an untitled project. If you undo past that step, the next sync puts the same key back for the session.

"Save as" and copies share the stored key, so both feed the same Blender source. Sync one at a time, or clear the source in Blender.

Teamwork: the key is a hash of the BIMcloud server URL and project name. Nothing is written to the shared project. Renaming the project on the server gives it a new key. Teamwork has not been tested.
