Turn reward touches into an unlockable Touch setting

Every entry gets a Touch setting next to its design, offering the 16 touches
the rewards carried, each unlocked by its reward. The reward designs that the
builder can now make are removed; only the underwater rain cloud and the
medium, hard and advanced egg hunt designs stay. Reward requirements move to
Unlocks, shared by touches, wing images and cosy smoke. The trail duration
moves to the particle row to make room in the design row.
