* fixed two bugs related to #1445, on BeOS R5, BFS has a bug that prevents

attributes to be written under a certain name when they already exist under
  the same name but with a different type
* the code that did the saving to a temporary file, then copied the attributes
  of the original file, then clobbered the original file prevented saving the
  icon in the icon attribute reliably, disabled this code for now and added
  TODO how it should work better
