Weak dependencies + 25 GA

Just a quick note that I've made a package push today. (and reverted the ffmpeg update to 3.1.x in f24 because of report: rfbz#4334). On a side note this time the repo was generated with newer tools, so in short it should be a step forward to have support for weak dependencies in RPM Fusion. (or maybe it even fixed it). If your package already use weak dependencies, it should now take effects in the current repos from f23/f24 updates and f25/rawhide. Please reminds that rich dependencies or boolean dependencies are still not allowed per Fedora Guidelines IIRC. If any side effects, please report an infrastructure bug. Thx -- - Nicolas (kwizart)
