Add .reverse_each support to bindings

[RickCarlino]

module Main
  class MainController < Volt::ModelController
    private
    def send_msg
      store._logs << {text: store._msg}
      store._msg = ""
    end
  end
end

  <form e-submit="send_msg">
    <input type="text" value="{{ store._msg }}">
  </form>

<ul>
    {{ store._logs.reverse_each do |log| }}
    <li>{{ log._text }}</li>
    {{ end }}
  </ul>

This code will load after a change happens to the collection, but not on page load. using each does not have the same issue.

I pushed to master a fix for doing .reverse.each, but currently bindings only support .each and .each_with_index. I'm adding this as a todo to add .reverse_each support in bindings.

Confirmed work around, for those who are hitting the issue:

{{ store._todos.reverse.each_with_index do |todo, idx| }}
      <tr>
        <td>{{ idx+1 }}.</td>
        <td><input type="checkbox" checked="{{ todo._completed }}"></td>
        <td class="name {{ if todo._completed }}complete{{ end }}">{{todo._name}}</td>
        <td><button e-click="remove_todo(todo)">X</button></td>
      </tr>
{{ end }}

@RickCarlino @ryanstout so are we still adding .reverse_each ??

[RickCarlino]

I think the consensus was that we wanted the feature, but that there were higher priority TODO items and the .reverse.each workaround was good enough for most folks. If you have time to take a stab at it, I'm sure it would be accepted into master, I've just been too busy to give it a go and the work around was 'good enough' for what I needed to do.
