Make New Swatch more intuitive and flexible
When 'None' is selected as current color (or no selection is active), the New Swatch menu item is grayed out, since New Swatch wants to copy the color of the selection.
When having a complex selection (lots of effort sometimes), it is rather dissapointing to not have the possibillity to give it a new color on the fly.
Why not make 'New Swatch' always available?
Intuitively, when no color is active, it should bring up a color selector panel, just like when an existing Swatch is double clicked.
(If you think this is confusing - add a menu item for 'New Swatch from selection')
We can alway create a swatch, independent of the selection.
In this way we can build a color scheme from scratch right in the Swatches Panel.
