feat(editor): two free ends joined without loops or forced curves, the shape from a free end on the wheel

Browse Source 
- the join of two free ends (a drag from one onto the other, or a click of the lay tool on it) tries in turn: a straight when the joints check can't see the kinks (half its angle), one circular arc through both ends (a piece cut out of a curve comes back as it was, its cant kept), a curve with straights where the tangents meet, a reverse curve, and only then a free Bezier curve; a curve turning more than it needs to, sharper than 10 m or longer than three chords is never taken
- the transition curves eased out of a curved neighbour only when there's room for them between the ends, never crossing each other into a loop
- cant and transition curves recommended for the radius the curve really gets, at the speed of the joined track or of the tool and never above what the radius allows; the circular arc keeps at least max(20 m, 0.4 V) between the transitions, the cant lowered to what the shortened transitions can ramp, transitions under 1 m left out
- shapes from a free end: arc then straight, straight then arc, arc through the cursor, straight; Ctrl+wheel steps the radius, Shift+wheel the shape (at a free end: the other joins), the plain wheel still zooms; a click of the lay tool from a free end lays the shape and goes on from its end
- self-test commands join, layto and joints; Polish translation
