10.2 HTML formatted columns

As a special case, a format of %h means that the test result field should be taken as ready-to-output HTML and should not be subject to further processing; this can be useful with custom-grader templates that generate HTML output, such as SVG graphics, and we have also used it in questions where the output from the student's program was HTML.

NOTE: %h format requires PHP >= 5.4.0 and Libxml >= 2.7.8 in order to parse and clean the HTML output.
