Changed news page to use JS to display relavent posts

News posts are stored in `news.yml` which Stasis compiles down to a tiny
JSON file.  The JS on the news page then sorts out the relavent posts
and puts them on the page.

TODO: Make real posts, re-enable Twitter widget
Controller tweaks:

* No weird namespacing, use "helpers"
* Tiny Regex optimizations
* Comments
Holy crap! works in IE >=6. Thank you, jQuery.

Turns out that the only thing holding me back was `Date.now()` which
only works in IE 9+ -- nothing a hideous hack can't fix
