[qet] don't translate abbreviations

[Jonas Stein <news@xxxxxxxxxxxxx>]

I propose to leave PNG as PNG in all languages

Example from the code:

	format -> addItem(tr("PNG (*.png)"),    "PNG");
	format -> addItem(tr("JPEG (*.jpg)"),   "JPG");
	format -> addItem(tr("Bitmap (*.bmp)"), "BMP");
	format -> addItem(tr("SVG (*.svg)"),    "SVG");

====

	format -> addItem("PNG (*.png)",    "PNG");
..
..
