The structure of content is like this:
```
<div class="post-content" data-role="post_content-text">
<div class="trix-content">
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd">
<html>
<body>
<div>
Unspeakable thing are written here<br />
<br />
haiiiiiiiiiiiiiiii hi hi hiii its meee back againnn, plspls leave a comment if uuuu liked it mwah
<3
</div>
</body>
</html>
</div>
</div>
<div class="post-uploads
```
Currently we extract content with:
```
(extr('<div class="post-content', '<div class="post-uploads').partition(">")[2])
```
I propose we just take the body parts:
```
extr('<body>', '</body>')
```
which only happen when surrounding actual content.
It is then easier to use it in the filename content with the `!H`
formatter: `content[:160]!H}`. Otherwise the content currently extracted
can't be decoded with it.
