audioOutputs/audioOutput_shout: adding timers back
The shout plugin will now feign playback until the connect timeout is hit, preventing connection attempts from blocking playback on local outputs. Note that this patch is very different from remiss' original one. git-svn-id: https://svn.musicpd.org/mpd/trunk@6738 09075e82-0dd4-0310-85a5-a0d7c8717e4f
