This time with more manual checking and using git blame -M -C, so that
a few cases of copied code get a copyright notice corresponding to
their initial introduction.
This is a whitespace-only patch. Hopefully, it'll only affect rarely-changed
parts of the engine, since all regularly maintained pieces should already
use tabs.
Most files using it weren't used by c4group-the-application anymore, and
the remaining stuff can be dealt with by using stubs or the same code in
both cases.
The BOOL->bool patch (ea7876ddd97d) changed the size of C4GroupEntryCore, thus
C4Groups could no longer be loaded correctly. This broke PlayerJoin for packed
player files.
The same patch seems to also cause other problems - normal Clonk movement
in the landscape is currently broken as well.
