- added readonly pointers. They need to be defined with 'readonly<classtype>'. These are significantly different from declaring a field readonly in that they do not disallow modification of the variable itself but what it points to. For the actor defaults this is necessary to prevent accidental modification. A readonly pointer is actually a different type than a regular pointer.

- fixed code generation for dynamic cast. It was missing the jump instruction after the compare.
