escape prop values unless the field is HTML - #162

Conversation
The `prop` helper passed item values to `tag` as a callback, so they were output without escaping. A value like `<script>...</script>` in any field (for example, a user-submitted name) became script on the page. Only output values as HTML for fields with `contentMediaType: text/html`, which the editor already uses for HTML fields. Everything else is escaped.
