* fixed the following change conditions where a player element is used
  as the "element that is triggering the custom element change":
  - touching <element>
  - hitting <element>
  - explosion of <element>
  - move of <element>
  (the last two conditions already worked partially, but only for the
  first player, and not for the "Murphy" player when using "move of")
