Remove unused code

[JoeBiellik]

This removes the incorrect and unused Internet Explorer conditional comment and JS.

Since the initial commit, the code has included some JS to set viewport options, behind an IE conditional comment. Unfortunately, this conditional comment is incorrectly formatted and therefore invalid.

A valid IE condtional comment must be in the form <![if !IE]>...<![endif]> or <!--[if !IE]><!-->...<!--<![endif]-->, however the code uses <!--[if !IE]>...<![endif]--> which all browsers will parse as a standard comment and ignore.

To the best of my knowledge, no browser has or will ever invoke this code, so this removes it entirely.
