// This custom plugin allows player flags to be inserted into the HTML content.
// It was adapted from the standard "template" plugin (which we can't use, since it *replaces*
// the whole of the HTML content, instead of *inserting* an HTML fragment). This version
// also allows the inserted content to be generated dynamically (to account for where images
// should be loaded from).
