ba6de1bcdf SCI: Added sanity checks for SCI3 scripts bigger than 64KB 
- Extended the "verify_scripts" console command for SCI3 scripts
- Added a check for such large scripts when scripts are loaded, with
an error for now, till a mechanism to support such scripts with a
16-bit addressing scheme is in place (e.g. overlaying, or splitting
scripts). Either way, such scripts should span over more than one segment

b6488818a5 SCI: Bugfix for rev #52688. 
We can't just set the lockers of script 0 to 1, as at that point
the objects associated with the script are marked to be deleted,
thus we need to reload the script
