Target "FX parameter: Set automation touch state"

This is similar to Target "Track: Set automation touch state" but for FX parameter value changes.

There’s one difference. This target currently only reacts to release events, not press events. So you can’t start writing automation by touching the fader. You can only end writing automation by releasing it. The reason is that REAPER doesn’t provide a function TrackFX_BeginParamEdit, it only provides TrackFX_EndParamEdit.
