Rewrites:

- rewrote detectCorePath() so it can handle more than one (.) path
- all my applications have this framework cloned to "./core/" and currently
  uses a symbolic link inc/ -> core/inc/. This is then no longer needed and
  should be removed from all projects. This surely implies that index.php has
  been distributed on all projects.
- later on this will be changed, then there is no class in index.php, but only
  one include file and one call to main() method.
