Create "Bibliography Entry" style
In order to implement #42 (closed), we'll need a "Bibliography Entry" style tag. Let's put it at the bottom of the "Display" style group and if the editors want to move it we can move it.
This tag is simply a container to identify the bib entry so it can be properly indented as in #42 (closed). It should leave inline formatting unchanged. So long as the indentation is visible in Wax, that should be sufficient to identify the style visually, so this won't need any other special display flourishes.
This tag doesn't mean that we can't look for bibliographies at import and do some auto-tagging, it just gives the editors maximum flexibility, as they won't be constrained to bibliographies with only bib entry elements in the component.
