Lera Elvoé f24906715d store connections inside the deck (#147)
- node/port connections are now stored in the deck they belong to
- share the connections object between group instances for free syncing
- add compatibility code to allow loading decks made before this change
- disabled the ability to open multiple decks in the renderer for now since it'd cause problems when opening multiple decks and one of them is incompatible; to be redesigned later

closes #140
