Handle ADD, INS, DEL, SUP consistently

[benwbrum]

We need to make sure that we're using semantic HTML tags correctly for add, ins, del, sup, marginalia.

Transcript

this is just a portion of hte text

this is the rest of the text.

This is a <del>DEL</del> tag.

This is an <ins>INS</ins> tag. (Not supported in our documentation, but autocompletes?)

This is an <add>ADD</add> tag.

This is a <sup>SUP</sup> tag.

It looks like the HTML standard for additions is ins rather than the add which we support. On the other hand, TEI uses an add element for additions and insertions.

We should treat these as synonyms with a TEI flavor vs. HTML flavor, converting add to ins on all HTML output and ins to add on TEI exports. I would prefer any ins tag to be styled in a superscript, the same way that we currently handle our add tags, though we can keep the underline for compatibility.
