Fix #798: the Curvature tool edits any selected path

Browse Source 
The Curvature tool only edited the path it was drawing. It now edits any
selected path, whatever drew it, keeping its shape except where edited:
a click on a point makes it the current (direct-selected) point and a
drag moves it, re-curving only its two segments (the neighbours keep
their handle directions); Alt-click or double-click toggles it smooth or
corner and Delete removes it; a click on a segment adds a smooth point
without changing the shape, and a drag moves it in the same undo step.
With an end of an open path current, clicks go on from it (the old
segments keep their shape) and a click on the other end closes it.

The edits go through a new path.curvatureEdit command (move, insert,
extend, close), path.convertAnchor and path.removeAnchor, one undo step
each. The tool now claims Delete/Backspace while it has a point to
remove, so the key no longer deletes the whole path.

## Editing a path with the Curvature tool
The Curvature tool edits any selected path, whatever drew it, keeping its shape except where edited (#798). Each edit
is one undo step and leaves the anchor it edited direct-selected (the tool's current point):
`path.curvatureEdit {id, subpath?, op, …}` answers `{anchor}`. `op: "move"` with `anchor`, `x`, `y` moves a point and
re-curves only its two segments: a smooth point turns along the line through its neighbours, and the neighbours'
handles keep their directions (their lengths scale with the chord), so the segments beyond don't change.
`op: "insert"` with `segment`, `t` adds a smooth point there without changing the shape (with `x`, `y` it is then
moved there: the tool's click-and-drag on a segment). `op: "extend"` with `x`, `y` goes on from the `end` (default)
or the `start` of an open subpath, and `op: "close"` closes it from that end; `from` says how the old end bends into
the new segment: `"keep"` (default) keeps its curve, `"smooth"` curves it through its neighbours (a point the tool
placed), `"corner"` leaves it without handles. Alt-click or double-click toggles a point with `path.convertAnchor`, and
Backspace/Delete removes the current point with `path.removeAnchor`.
