Enable presentationMode in Internet Explorer 11

*(I just realized that I had forgotten about this patch, after finishing it a couple of weeks ago.)*

This PR enables presentation mode in Internet Explorer. Note that it will only work in version 11, since that is the first version of IE that supports the Fullscreen API: http://msdn.microsoft.com/en-us/library/ie/dn265028%28v=vs.85%29.aspx.

*__Just a note for anyone wanting to test this:__ IE11 does not include the compatibility mode which allows you to test pages in previous versions of the browser (such as IE10, IE9, ...). By installing IE11, you are no longer able to easily run older version of IE.*
