- added the missing handler for reading Timidity configs from the lump directory. - fixed incomplete init of the GUS synth when no soundfont can be located. - fixed bad initialization of WildMidi sampling frequency. It would default to 11.025 kHz if no valid rate was set. Now it will use the sound device's native frequency.
