Style for place=island|islet

[naoliv]

Should we start to display areas with place=island or place=islet with some styling?
As they are now they are displayed as any other non-tagged way (with a gray color)

In 13394/josm:

• fix #15648 - warn about unclosed ways with place=islands
• fix #15659, see #12043 - always display place=island and place=islet fill color (and name) independent from the place style setting. Regression of r8986.
