-------------------

This one reverts part of the PR 4319 which was aimed to allow child titles to inherit bundle settings.
The fix seems good so far, but by applying it to save folders caused a trap:
Now child's save folders move to bundle folder, hence saves will vanish, and the android/qt save tools are still pointing to old folders.
Since the save part was only a compliance fix, instead of fiddle in master i'd rather revert this part now, then only touch this again if any bug show up.
No worries. I'll be right here waiting.
