[PlanetCCRMANews] testing: new jack, new ardour 2.4

[Fernando Lopez-Lezcano]

Available on the Planet CCRMA testing repositories for fc6/7/8:

- new jack (combination package of jackd and jackdmp). 
- new ardour, 2.4-1[*]

Enjoy!

[*] last I checked (2.3.1), ardour had a problem on fc6 with the fonts
being too big for the bounding boxes. 2.4 has a new global font scaling
setting that probably will fix that.
