penPlus.isIFrame is backwards

[LegoBrainBiker]

 //Remove the export button if we are in an IFrame
  if (window.location === window.parent.location) {
    penPlus.isIFrame = true;
    fileDropdown.removeChild(importButton);
    fileDropdown.removeChild(exportButton);
  }

should be

 //Remove the export button if we are not in an IFrame
  if (window.location === window.parent.location) {
    penPlus.isIFrame = false;
    fileDropdown.removeChild(importButton);
    fileDropdown.removeChild(exportButton);
  }
else {
    penPlus.isIFrame = true;
}

although penPlus.isIFrame is never used, and everything works fine currently.
