Recolor Artwork: color sliders edit the selected row's new color in a chosen mode

Browse Source 
The Assign tab gets a Color Mode menu (HSB, RGB, CMYK, Lab, and Tint when
the row's new color is a spot color of the Limit to Library library) and
its sliders under the rows. They edit the first selected row's new color
and are disabled with no row selected. Once they have edited a color in a
mode, the preview and OK send recolor.apply with model "new", so the art
takes the color in that mode.

recolor.apply rows take an optional tint (percent, default 100): art linked
to the row's global or spot library swatch takes that share of its tint.
recolor.randomize keeps a row's tint.

`recolor.apply` on the canvas; confirm keeps it as one undo step (with a group, the group is rewritten in the same
step; with no art selected only the group changes). In the Swatches panel, double-clicking a colour group's folder,
