[BZ 1000173] - Missing Disabled icons (404 not found) - when resizing the portlet, SmartGWT change the icon to the '_Disabled' form, but the icon was missing for 'Package_16.png'. I've added all kinds of portlets and it was the only one missing.
[BZ 1020874] - Add subscriptions button on platform->Content->Subscriptions tab displays HTTP Status 404 in UI - adding the form action JS hack
[1035420] OOB content labels get cut off
This portlet could use some more TLC, but at least now the metric name should
appear in full.  Added some better formatting to the list entries.  Note that
LinkItem.setClipValue(false) needed to be set explicitly despite being the
documented default.
