Additional tagged_with options

Added options to tagged_with for reversed, limit, and page #.

Here’s an example (from ideal808) of using it on the frontpage slider:

<div id="slider" class="clearfix">
  <ul>
    {% for i in (1..5) %}
    <li>
    {% tagged_with 'Frontpage Slider' do products limit:4 page:i %}
      <table cellpadding="0" cellspacing="0">
        <tr>
        {% for product in products %}
          <td{% if forloop.first %} class="first"{% endif %}>
            <div>
              <a class="sliderImgLink" href="{{ product.url }}"><img src="{{ product.main_photo | photo_url: "medium" }}" width="100" height="100" /></a>
              <a class="sliderProductName" href="{{ product.url }}">{{ product.name }}</a>
              <span class="sliderProductPrice">{{ product.price_range }}</span>
            </div>
          </td>
        {% endfor %}
        </tr>
      </table>
    {% endtagged_with %}
    </li>
  {% endfor %}
  </ul>
</div>
