Allow reordering fx, captures and presets

I feel like using the app would be easier and faster, if we could move things around.

  • FX: When creating/copying presets I almost always need to move a FX block to another slot (e.g. move an EQ to make room for Doubler etc.). At the moment it seems that I have to manually add the block to another slot and copy the settings by hand.
  • Presets: Reorganizing the “All presets” list would make life easier. Maybe even adding some custom categories and a search functionality like in the IR view.
  • Captures: Reorganizing the banks in the bank list view without having to swap the captures one by one.
