SCI: multiple changes for mother goose vga

which is sci1 and sci1.1
fixes bug #3051145
- separating this mother goose from ega and sci2.1
- adding workaround when restoring saved games in these games, games try to calculate restored savedgameid instead of looking it up, we patch this code out and also set the global to the current savedgameid
- adding workaround for scripts checking savedgameid to be below 13 (our savedgameids begin at 100 now)
- changing official range for savedgameids from 1000->1999 to 100->199, otherwise mother goose would have required much larger patches and this range should be fine even if we replace savedgame dialogs later
