[jdom-interest] JavaDoc change for Document.java

[Elliotte Rusty Harold]

In Document.java,

    /**
     * This <code>Document</code>'s
     *   <code>{@link Comment}</code>s and
     *   the root <code>{@link Element}</code>
     */
    protected List content;

should be something like this:

    /**
     * This <code>Document</code>'s
     *   <code>{@link Comment}</code>s,  
     *   <code>{@link ProcessingInstruction}</code>s and
     *   the root <code>{@link Element}</code>
     */
    protected List content;

That is, add processing instructions to the list of legal content. This
is a documentation change only.
