Create help page for <context> tag
The <code><nowiki><context> ... </context></nowiki></code> tags process their ConTeXt contents on the fly and include the result on the page as an image. Whitespace is cropped out. The following options are available:
* <code>source=yes</code> displays the source before the output.
* <code>text="some text"</code> places 'some text' between the source and the output.
* <code>mode=mkiv</code> ensures [[Mark IV]] is used instead of the default Mark II.
