Allow for raw content interpolation

[mnelson]

Raw interpolation is defaulted to {{{= content }}}. I'm open to other delimiters but chose this to be consistent with mustache / handlebars and still consistent with the interpolation syntax used in sudo.

This is useful if you have a view which pre-processes content and generates html.

Example:

// in your view

urlRegex: /\(?\b(https?://|www.)([-A-Za-z0-9+(&)@#(/)%?=~_()|!:,.;]*[-A-Za-z0-9+(&)@#(/)%=~_()|])/g,

render: function render() {
  this.model.set('linkedContent', this.linkify(this.model.get('content')));
  this.$el.html(template(this.model.data));
},

linkify: function linkify(content) {
  return sudo.escape(content).replace(this.urlRegex, '<a class="inline-link" href="/redirect?url=$1$2" target="_blank">$1$2</a>');
}

<div>
  <h2>{{=data.title}}</h2>
  <p>{{{=data.linkedContent}}}</p>
</div>

If this is accepted into master I'll update the wiki documentation
