Bug free (?) final version

Corrected bugs:

• In the keyboard scanning routine - should now work on all CPCs and plus models
• In the tilemaps. No more getting stuck in the castle walls (unless you are careless with the walk thru walls potion)
• Now resetting the collected diamonds to 0 when starting a new game - no more accumulating through multiple games ;-)

Also:

Extended easter egg whe winning the game.

Thank you for playing and for your support!
