I have written a click track generator, "Metronome", that outputs a wave file.  You can adjust the sound of the click and program tempo changes through a text file.  
There are no options for swing type feels, but any meter is supported.  It is command line only and not open source yet.    
A word of caution, if importing into Ardour be sure to change the output name to something besides click.wav.
