Bug 301133 Unhide the linked resources locations tab in the Linked Resources property page
The mentioned tab was hidden in M5 since it needed polishing. There are new icons in the page, so when this bug is fixed, I will raise another one to track creating new icons by our UI designers.

				Object[] objs = { BROKEN, ABSOLUTE, FIXED };
				for (int i = 0; i < objs.length; i++) {
					Object[] children = getChildren(objs[i]);
					if (children != null && children.length > 0)
						list.add(objs[i]);
				}
				return list.toArray(new Object[0]);
			} else if (parentElement instanceof String) {
				if (((String) parentElement).equals(BROKEN))
					return fBrokenResources.values().toArray();
