Exchange plain html example with Coder generated examples

[FlorianFehring]

The most documentation pages uses HTML fragments like:

<fieldset>
                <legend>VIEW-Requestor</legend>
                <pre><code class="lang-html">
&lt;div id="present_example2" swa="Present FROM exampledata_list TEMPLATE table_for_all_datasets"&gt;&lt;/div&gt;
        </code></pre>
            </fieldset>

This makes problems when examples change: Often the functional code is updated but not the documentation code. to avoid this. All those HTML framents should be replaces by use of the Coder component. Example:
<div id="present_example2_html" swa="Coder FROM #present_example2"></div>
