Add option for a media toggle link, which would switch between media types.

This option could allow you to specify media types that can be toggled by the 
users by clicking a link (similar to the low-fi/hi-fi 
link).

Syntax might look something like this:

enhance.toggleMedia(['screen', 'screen and (max-device-width: 480px)']);

toggleMedia could accept an array of media types to toggle upon refreshing the 
page, essentially switching which files are 
directed to which device. This would allow us to create a link that says "View 
mobile site", and clicking it would set a cookie of 
something like:

enhancetogglemedia="['screen', 'screen and (max-device-width: 480px)']";

...and then refresh the page. with that toggle applied, a different link could 
be appended that says "View desktop site", which 
would just remove that cookie and refresh the page, restoring it back to where 
it started.
