Make crop a Photos-style tool with undo and actual-size view

Crop is now a mode like Draw/Redact: a draggable rect with corner and
edge handles, rule-of-thirds grid, dimmed surroundings, Cancel (Esc) and
Crop Image (Return). Re-entering crop after a crop shows the full
original with the handles on the current crop region, so it can be
dragged back outward; every crop is undoable from the toolbar.

The result window also gains an Actual Size view (Cmd+0): one image
pixel per screen pixel, scrollable, so retina captures stay crisp
instead of being resampled down to the window size.
