Parses content and returns parser output.

See the various prop-modules of action=query to get information from the current version of a page.

There are several ways to specify the text to parse:
 * 1) Specify a page or revision, using $1page, $1pageid , or $1oldid.
 * 2) Specify content explicitly, using $1text, $1title , and $1contentmodel.
 * 3) Specify only a summary to parse. $1prop should be given an empty value.
