[ACTION REQUIRED] Retiring packages for Fedora 20 v2

[Till Maas]

The following packages have been retired:

alsa-oss
firmware-extract
firstboot
gkrellm-timestamp
guiloader
justmoon
lybniz
mars-sim
miau
openstack-tempo
osgal
python3-cherrypy
vblade

Because alsa-oss was retired, mumble needs to be rebuild without OSS
support (just removing the BR failed in a scratch build because
libspeechd.h cannot be found, maybe this is an unrelated bug)

modplugtools needs to be changed to not ship modplugplay anymore, but
modplug123 should still work.

I will soon post a follow-up message regarding FTBFS packages.

Regards
Till
