Enable various "grouping" ARIA roles by exposing them as AXSubroles.

There are a large number of ARIA "grouping" type roles. On the Mac, it seems that the best fit is to make them into AXGroups with specific subroles that describe what they are

+        default:
+            return nil;
+    }
    return nil;

If you were to omit the default case in the switch statement then we'll get a
convenient warning if we ever add a new enum value without updating this switch

+<div role="status">text</div>
+<div role="tooltip">text</div>

Can we give these more useful contents than "text" so that the output makes a
little more sense?  Even using just the name of the role could be clearer.

+    if (window.accessibilityController) {
+          // this text field should be required.
+          document.getElementById("body").focus();
+          var obj = accessibilityController.focusedElement;
+          var subroles = new Array("AXLandmarkApplication","AXDocumentArticle","AXLandmarkBanner","AXLandmarkComplementary",
+                          "AXLandmarkContentInfo", "AXDocument", "AXApplicationLog", "AXLandmarkMain", "AXApplicationMarquee",
+                          "AXDocumentNote", "AXLandmarkNavigation", "AXDocumentRegion", "AXLandmarkSearch", "AXApplicationStatus");
+          for (var k = 0; k < 14; k++) {
+              var succeeded = obj.childAtIndex(k).role == "AXRole: AXGroup" && obj.childAtIndex(k).subrole == "AXSubrole: " + subroles[k];
+              shouldBe("succeeded", "true");

The failure case of this "shouldBe" will say only that succeeded should be true
but is false, which is impossible to understand without studying the test.  I
think it would be clearer to use a separate shouldBe for each half of the
shouldBe("obj.childAtIndex(k).role", '"AXRole: AXGroup"');
shouldBe("obj.childAtIndex(k).subrole", '"AXSubrole: ' + subroles[k] + '"');

Then any failure message would be much clearer about which part of the
expression is failing and why.  It'll also make the expected result more
