ext/timidity/gstwildmidi.*: Initialize wildmidi only once in the plugin init function instead of once for every insta...

Browse source 
Original commit message from CVS:
Based on a patch by:  Sonicadvance1 at GMAIL dot COM
* ext/timidity/gstwildmidi.c: (gst_wildmidi_init),
(gst_wildmidi_change_state), (plugin_init):
* ext/timidity/gstwildmidi.h:
Initialize wildmidi only once in the plugin init function instead
of once for every instance. The second and following calls to the
wildmidi initialization function will fail. Fixes bug #525613.
Also don't register the element at all if wildmidi initialization
fails.
