Possible to add shading (gradient) in addition to color.

Internal modifications mainly regarding icon creation.
Newly replaced custom icons of alias/symlink and items on the Desktop and in the list view are visible only after Finder-relaunch (or any other events forcing Finder to update). To relaunch Finder, use the message panel’s "Relaunch" button or manually, e.g., click the Finder icon in the Dock with the option (⌥) key and select "Relaunch". Alternatively, first remove the old custom icon and then attach a new one.
