Some GWT pages are not working on IE

If you go to the node's page, the GWT component that shows the IP/SNMP interfaces appears empty on IE10 and IE11.

Now, if you open the developer tools, and then change the IE compatibility to be 9 or greater, the GWT component works fine.

OpenNMS is forcing the compatibility mode to be 8, which means, newer browsers are going to work like "IE 8".

If we change this setting in OpenNMS to use the latest API available on IE:

<meta http-equiv="X-UA-Compatible" content="IE=edge"/>

The GWT component works as expected.
