implement Timidity support

[datajake1999]

I am working on a VSTi version of Timidity 0.2i, and have made the synth easier to integrate into other projects. Adding Timidity to foo_midi itself would allow the use of Gravis Ultrasound patches for MIDI playback. The repo for my VSTi can be found at https://github.com/datajake1999/Timidity_VSTi

It should work out of the box. The VSTi is loaded by vsthost__.exe and the component communicates with it to render MIDI.

The VST works in foo_midi, however the current state of VST support results in settings not getting saved upon exit.

Yeah, I got another report about the settings. I'll look into it. Not sure how it got broken.
