Fixes for fluidsynth >= 2.0.0 (#766) 

* Fluidsynths: Ensure fluidsynth's defaults are set once and in one place

This makes transition fluidsynth 1.x -> 2.x a lot easier.

Signed-off-by: Andreas Müller <schnitzeltony@gmail.com>

* Enable support for fluidsynth >= 2.0.0

This reverts commit e67ba7c25b.

* Fixes for fluidsynth >= 2.0.0

* preset iteration and getters have changed
* constants for most defaults are no more available in public headers -
  fluidsynth wants to be asked
