A follow-up on a previous PR GH-41. The discussion in the forum can be
viewed at http://forum.openclonk.org/topic_show.pl?pid=33086.
Run clang-tidy (without auto, pass-by-value and using checks) to fix the
header files not modified in the previous PR.
Summary of the changes:
- C++11 member initialization.
- nullptr instead of 0 for pointers.
- override for functions declared virtual in base class.
- default trivial special member functions
