Change icon for the layer tools in the layer manager panel on the map…

… page.

The tools in the layer manager in the map are opened on hover. But the icon was misleading, it invited you to click on it. When you hovered the layer the icon disappeared leading to the thought that you couldn't click the icon and therefore couldn't open a menu and missing some extra options (that weren't there).

The tools are still opened on hover, making it clickable asks for some rebuilding, but the icon has changed and the color is dimmed.
