I'll implement some code to allow Twig templates to be used along side our current PHP templates.

Ok, added Twig library and changed prefetch to allow both Twig and PHP templates to coexist.

In order to do this, we need to follow this convention:  

each Twig template must have this line at the top
{# <?php $is_twig = true; ?> #}


This is what allows prefetch to know what is a Twig template, and what is PHP.  When we're not using PHP templates anymore, we can stop this convention.

Here's an example,

I'll work on adding a base template and some useful extensions to Twig, so we can do things like,

{% download_button %}
{{ url('firefox/all') }}
{{ img('firefox/whatever.png') }}
{{ style('tignish/foo.css') }}
etc

After pondering this for a long time, Twig might not be the best option, because it's such a big syntax change.  

http://phpti.com/
^ has most of the same features, most importantly inheritance, and uses the same PHP syntax we're already using.  Could be a better option.

I'm going to remove any Twig code I implemented.
