Alexia Death 06c1b290d0 app: Add tool preset editor to controll what elements get applied
I had to remove the asserrt in tool preset constructor, because with it
it wasnt possible to initalize an empty model object for the editor.
At init time the gimp object passed to the constructor is not yet available.
