Fix QSettings problems: - Reopen file in ReadOnly mode if it was open in ReadWrite mode and is being read. This is needed for stupid QSettings which opens file in ReadWrite mode just to call readAll() on it. - Implement setSize(0)

#
#  FIND_LIBRARY_WITH_DEBUG
#  -> enhanced FIND_LIBRARY to allow the search for an
#     optional debug library with a WIN32_DEBUG_POSTFIX similar
#     to CMAKE_DEBUG_POSTFIX when creating a shared lib
#     it has to be the second and third argument
