org.jboss.tools.common.model.util.ModelImages has image leaks

from line 33:

	public static Image getImage(String key) {
		return instance.createImageDescriptor(key).createImage();
	}

try to inspect Call Hierarchy of the function - there are a lot of places with Image leak here.
imo, getImage is not correct name here -> should be createImage in minimum, maximum is necessary to change logic.
