Message:

Changed conversion_cast≠() to omni_cast≠() and added support for dynamic_cast.
Whenever you want to convert 2 pointers, it uses static_cast if the conversion is implicit (derived to base class) and dynamic_cast otherwise.
There is a drawback however: When static_cast is not possible and at least one of the two pointers is not from a polymorphic class, you get a compiler error that tells you exactly this. But who would want to convert an int* to OrxonoxClass* ?
