Replaced the graphics resource with an updated one for Spooked.

New graphics resource had a few scenery inconsistencies possibly due to
extra blank tiles in the original. These imperfections have been
corrected as well in the world

Finally removed the extra lives in Spooked at the start.
Fixed a cobweb on screen 999 for Spooked
Addes a bigger subset of Spooked to the default pack, and takes that
subset from the new version (with the improved graphics). Fixes #63
