Please don't release hdspmixer without having the preset load/restore
issue sorted out.

The ondisk structure contained no meta information, so it's already hard
enough to tell which version of hdspmixer created a given preset file.

Having more officially released versions available complicates things.
I've recently introduced a magic header for the new ondisk structure,
but it isn't stable, yet.

While I think it's perfectly acceptable to have unstable ondisk
structures during development, I would like to have a stable format
when releasing.

Current plan:

  - no magic: old (pre v1.0.24 format or broken v1.0.24.(.1))
  - v1 style: fixed format, maybe will become v1.0.24.2
  - v2 style: only single card instead of three cards in one preset file

Just my €0.02
