* fixed bug with dynamite dropped on top of just dropped custom element
  (collect dynamite, collect CE, drop CE => dynamite was also dropped);
  dynamite can still be dropped, but drop key must be released before
* fixed bug with wrong start directory when started from file browser
  (due to this bug, R'n'D could not be started from KDE's Konqueror)
