Changelog For Org-Mode Snippets

---

It looks like these were edited with an editor that auto-inserted a newline on
save, so I removed them. videos, links, and images have had the plural "s" removed. The rest
of them are improved to reduce annoyance (described below).

Issues

img

Too many newlines; nonidiomatic usage of closing tag.

Old expansion

<img src=""
alt="" align="left"
title="image title"
class="img"
</img>

New expansion

links
