Handle "details" macro

[osnard]

Source:

<ac:structured-macro ac:name="details" ac:schema-version="1" ac:macro-id="...">
	<ac:rich-text-body>
	<p class="auto-cursor-target">
	<br /></p>
	<table class="wrapped">
		<colgroup><col /><col /></colgroup>
		<tbody>
			<tr><th>Field 1</th><td>Value 1</td></tr>
			<tr><th>Field 2</th><td><div class="content-wrapper"><p><ac:structured-macro ac:name="status" ac:schema-version="1" ac:macro-id="fc045cc6-ca0f-4cba-815f-a3e95619713c"><ac:parameter ac:name="colour">Red</ac:parameter><ac:parameter ac:name="title">HIGH</ac:parameter></ac:structured-macro></p></div></td></tr>
			<tr><th>Field 3</th><td><div class="content-wrapper"><p><time datetime="2020-04-15" />&nbsp;</p></div></td></tr>
		</tbody>
	</table>
	<p class="auto-cursor-target"><br /></p>
	</ac:rich-text-body>
</ac:structured-macro>

Proposed output:

{{Details
|items=
{{Details/Item|Field 1|Value 1}}
{{Details/Item|Field 2|{{Status|color=Red|title=HIGH}}}}
{{Details/Item|Field 3|{{Datetime|2020-04-15}}}}
}}

SMW attributes should be used for meta data storage.

Hint: "Details" macro can only contain a <table>. First and second column serve as Key/Value. Further columns are just custom text. Should still be preserved.
