Yet another variant on how to find data files 

This time, the relocation code checks for a "System.c4g" in either
the executable path or a "data" folder directly below. CMake makes
sure that this points somewhere sensible for normal builds.

TODO:
* Check whether this actually works under Unixes. Can "ln -sf"
  delete important stuff? Is there a safe alternative?
* Further unify with the Mac Os solution. Other platforms might
  auto-pack for release builds too, for example - and it might
  be a good idea to have a proper data subdirectory in Mac bundles
  as well.
