Internet Explorer 11 not working browser warning.

Related to ticket #1575 Internet Explorer 11: caUserCert request submission fails using the EE page.

This patch will only do the following:

Detect IE when IE11 is being used. Before this IE11 was mistaken for Firefox.
Detect IE11 specifically and warn the user that there is no support.

This ticket will live to se we can fix this properly by porting the current
VBS script to Javascript to support cert enrollment on IE 11.
