Implement artboards and document version enforcement (#466)

* - graphite document artboard implementation
- autosave document load hitch fix
- Autosave will delete saved files when graphite document version changes

* formating

* - top left 0,0
- fixed hitch on first document
- vue calls first render

* Revert

* Merge branch 'master' into artboards

* Small bug fixes and code review tweaks
