Handle structured drag and drop

The Discrete Math Primer course includes a drag and drop activity whose layout file structure the course digest tool does not support. We need to extend the digest tool to detect instances of these layout files and convert them to the Torus drag and drop questions.

In this branch of the course:

https://svn.oli.cmu.edu/svn/content/principles_of_computing/discrete_math_primer/branches/v_1_7-echo

In this file:

content/x-oli-inline-assessment/simplifyinged910f36bd6f4ded910db99c90244fd3.xml

You will see the first question has in its stem:

<body>
                <p id="de187e55735144589ded38de1bfca9f3">Practice completing a conversion of \(\neg
                    p \vee q) \wedge (p \vee \neg q)\) to a disjunction of conjunctions by dragging
                    and dropping each of the blue intermediate steps below into the correct order.</p>
                <custom id="d7076c00a1d54915bdbbd71cc0040632" type="javascript" logging="false"
                    src="../webcontent/DynaDrop/DynaDropHTML.js" width="100" height="100"
                    layout="../webcontent/DynaDrop/d7076c00a1d54915bdbbd71cc0040632_layout.xml">
                    <param name="showInputs">false</param>
                </custom>
            </body>

That layout file uses a different structure than other layout files:
