forward declarations used to untangle interdependet classes.
- basically, everywhere in header files we removed '#include' lines were only pointer to the respective classes were used and the include line was moved to the implementation file.
- as a sidenote, lots of funny errors happened because headers were included via a nesting over three other includes. Now, all should be declared directly as needed, as only very little include lines remain in header files.
