* fixed bug which caused all CE change pages to be ignored which had
  the same change event, but used a different element side
  (reported by Simon Forsberg)
* fixed bug which caused elements that can move and fall and that are
  transported by a conveyor belt to continue moving into that direction
  after leaving the conveyor belt, regardless of their own movement
  type; only elements which can not move are transported now
  (reported by Simon Forsberg)
* fixed bug which could cause an array overflow in RelocatePlayer()
  (reported by Niko Böhm)
* changed Emerald Mine style "passable / over" elements to "protected"
  (fixing unsolvable level 10 of "Bondmine 9" with bug beside gate)
* added new option to select from which side a "walkable/passable"
  element can be entered
* added explosion and ignition delay for elements that can explode
* fixed bug which caused player not being protected against enemies
  when a CE was "walkable / inside" and was not "indestructible"
* added "walkable/passable" fields to be "protected/unprotected"
  against enemies, even if not accessible "inside" but "over/under"
