SMSound onwarning and onfailure options for NetStream / RTMP error/exception handling. Removed additional sound param on onfailure() callback, apologies if this breaks anyone's implementation (disclaimer: these options are still experimental, undocumented. :D) "Unhandled" exceptions are now considered non-fatal, using onwarning instead of presuming playback has failed etc.
