This was done after the players had already been created. To ensure that everything gets set properly it is necessary to pass the desired sample rate to the device's constructor and let it make sure that a proper sample rate gets set.
- implemented a fallback both for sound font lookup and for MIDI device selection so that if some non-working combination is set up, the player will fall back to something that works.
- 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.
- added arrays to the config to hold entries for the softsynths' config files. This is not active yet, but will later be used to give the user a list of config options instead of having to type it by hand.
