Quick way to give warnings if javascript and/or cookies are not enabled. Will want to tweak so the code isn't redundant, and ideally so check for cookies doesn't rely on javascript.

And we'll want to expand the texts.
Tweaks to display javascript and cookies warning:
* will only display cookies warning if javascript is enabled.
* remove redundant code
* tweak noscript html to display better div
