Remove HTML5 option from Horizon View users.

This is a longshot, but I was asked the question and I'm tasked with providing the answer.

Our Horizon View environment does not currently support HTML5. To avoid confusion with the users, the managers would like us to remove the HTML5 option from the end users.

It seems unlikely that I'll be able to remove the HTML5 button from the popup window. But an iRule added to the VPE may be able to direct users down the Horizon View Client path without being prompted.

Is this something that can be implemented easily?
