SCI: Some slight work on SCI3

- Enabled the SCI3 game entries for testing purposes
- The resource manager is initialized fully now (with a slight hack)
- Added a hack for the demo of Shivers 2 (which seemingly has no
scripts or vocabularies)
- The engine will stop before parsing any game scripts in SCI3 games,
and opens the console for resource manager-related functionality
