+ * 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")
