As per commit ed7ea51fb7, reintroduce
the "Fade" functionality for filters, by incorporating it directly
into GimpFilterTool.
Add "mode" and "opacity" options to GimpOperationSettings, and add
a corresponding "Fade" expander to the GimpFilterTool dialog
allowing to control them.
Reintroduce the FADE layer-mode context, and use it to mark the
layer modes avaialable for fading.
