Post content not processed correctly

Linebreaks in the raw download post content are converted to <br> instead of <p>.

As an example the post content created in TinyMCE

My first paragraph.

My second paragraph.

My third paragraph.

is rendered on the site as

html
My first paragraph.<br>
<br>
My second paragraph.<br>
<br>
My third paragraph.<br>

but should be

html
<p>My first paragraph.</p>
<p>My second paragraph.</p>
<p>My third paragraph.</p>

In addition brs are also added in lists, which leads to an empty line after each list item. The html:

html
<ul>
 	<li>one</li>
 	<li>two</li>
 	<li>three</li>
</ul>

is rendered as

html
<ul><br>
 	<li>one</li><br>
 	<li>two</li><br>
 	<li>three</li><br>
</ul><br>

This was quite surprising and killed the design of the theme.

The fix is to use wpautop in favour of nl2br. In shortcodes.php on line 254 it should be:

wp_kses_post( wpautop( $download_text ) )

The same is in line 568.
