Add support for escaped coffeescript in syntax highlighting

[HarlemSquirrel]

Hi, could you provide a code sample so I can see the highlighting work? Thanks!

Here's a sample, funny enough it looks like GitHub doesn't support hamlc either.

.custom-select
  %select
    - @section.get('options').forEach (option) =>
      %option{value: option.cid, selected: if option == @section.get('current_option') then true else false}
        #{option.get('label')}

!= JST['sections/info'](@)

This doesn't appear to be valid haml

➤  cat test.haml
.custom-select
  %select
    - @section.get('options').forEach (option) =>
      %option{value: option.cid, selected: if option == @section.get('current_option') then true else false}
        #{option.get('label')}

!= JST['sections/info']

➤  haml -c --trace test.haml
test.haml:4: syntax error, unexpected ';'

➤  haml --trace test.haml

It was intentionally not valid Ruby Haml, this is Haml Coffee (an implementation of Haml in CoffeeScript)

Here's my results from running this locally, test.hamlc is the same that I pasted in my initial comment. If you're not familiar with Haml Coffee - this is working as intended.

    window.HAML = {};
  }

  window.HAML['/Users/adamrunner/test'] = function(context) {
    return (function() {
      var $c, $o;
      $c = function(text) {
        switch (text) {
          case null:
          case void 0:
            return '';
          case true:
          case false:
            return '“' + text;
          default:
            return text;
        }
      };
      $o = [];
      $o.push("<div class='custom-select'>\n  <select>");
      this.section.get('options').forEach((function(_this) {
        return function(option) {
          $o.push("    <option value='" + ($c(option.cid)) + "' selected='" + ($c(option === _this.section.get('current_option') ? true : false)) + "'>\n      " + (option.get('label')) + "\n    </option>");
          return '';
        };
      })(this));
      $o.push("  </select>\n</div>");
      $o.push("" + $c(JST['sections/info'](this)));
      return $o.join("\n").replace(/\s([\w-]+)='“true'/mg, ' $1').replace(/\s([\w-]+)='“false'/mg, '').replace(/\s(?:id|class)=(['"])(\1)/mg, "");
    }).call(context);
  };

}).call(this);

Sorry, I was in a rush when I first looked at this. This seems to work great!

[adamrunner]

No worries! Thanks for the merge!
