Wrong handling of filenames with multiple dots for window title

[bassklampfe]

Take a label file named "USB-Mini-et.al..glabels"
Window title is displayed as "USB-Mini-et", but it should be "USB-Mini-et.al."
As far as I can read from the source, in QString Model::shortName() should change

				QFileInfo fileInfo( mFileName );
				return fileInfo.baseName();

to

				QFileInfo fileInfo( mFileName );
				return fileInfo.completeBaseName();
