Icon for debugger in the toolbar

[badetitou]

It would be great to have a different icon for the debugger in the toolbar. In Pharo12, we always have the same icons

In the above example, the same icon for a playground and a debugger. It forces to read to retrieve its debugger

From what I dig so far, the bugs comes from a modification in the way to deal with Icon. It led to a modification of the TaskbarItemMorph>>#initializeFor: aTaskbar method. To use the line of the

self iconFormSetNamed: self model taskbarIconName

However, self model taskbarIconName does not return always the icon we want. Can modify the default behavior of taskbarIconName or the assigned model. I don't know what would be the best for now
